What Is TXID or How to Find a Transaction in the ... - Bitcoin

What is this? I sent some Bitcoin from Blockchain to Binance 55 Hours ago. Still no confirmation. TXID- ee604d44de5c80c69a922589ec0312b0efb37240bd0eff14e3908d1ae47ee311

So back in 2014 I put 60 bucks into a bitcoin mining service. Lost the seed but I have all the txIDs on Blockchains website.

So when I was a kid I put 60 bucks into bitcoin miner hashflare.io then I deposited it into dark wallet, a few years later when bitcoin started taking off i tried to recover the wallet but I lost the seed. But while going through hashflare I found all the TxIDs from my hashflare withdrawls. I followed that onto blockchains website and now I can see the amount I have now, is there any way to transfer it off of Blockchain and into my current wallet?

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

The power of "import electrum" as a python bitcoin scripting engine

I've been a big fan of Electrum as a wallet for a while now. Traditionally, when I wanted to do bitcoin scripting I would use either trezorlib, pycoin, or bitcoinlib. But recently I was digging a bit deeper into the Electrum source and found it to be one of the simpler python libraries to use to craft bitcoin transactions.
One of the nicer things about Electrum as a scripting engine is that you can drop the standalone app or AppImage on a system and run your scripts directly through the console. This makes doing things on Tails or other locked down systems much easier. To run one one of your scripts (without the event loop) simply type (assuming you correct the file path):
with open(r"myscript.py", 'r') as s: exec(s.read())
Obviously only do this with scripts you've personally authored. Never run random code on your machine especially when wallet private keys are in play.
There are already some great scripting examples in the electrum\scripts folder, but most of these use the event loop which brings in a lot of overhead. I found simple TXN processing can easily be done without spawning an full electrum thread. I'd be happy to PR the samples if there is any interest in this style from the maintainers.
Here's two examples I put together that craft a BIP65 spending transaction. It turned out to be much simpler than I imagined. I did it both in bitcoinlib and electrum. The structure is very similar and should hopefully be easier to follow. Feel free to start a PythonRoastMe on it.
Two things of note. I had to disable R-value grinding (nuked while loop) so that I had parity with bitcoinlib, which hasn't rolled it out yet. This is why the TXIDs differ. I also had to override the the PartialTransaction.get_preimage_script method since it makes certain multisig assumptions that don't apply to generic scripting.
Reference: * Electrum script to spend an OP_HODL P2WSH address (txid 3a461e6...78de2b6) * Electrum script to spend an OP_HODL P2SH address (txid a8110bb...3dadc93) * BitcoinLib script to spend an OP_HODL P2WSH address (txid 3a461e6...78de2b6) * BitcoinLib script to spend an OP_HODL P2SH address (txid a8110bb...3dadc93) * TXID 3a461e6...78de2b6 (P2WSH) on the blockchain * TXID a8110bb...3dadc93 (P2SH) on the blockchain * BIP-0065: OP_CHECKLOCKTIMEVERIFY (aka OP_HODL) * BIP-0141: P2WSH symantics * BIP-0016: P2SH symantics

Sent wrong amount to bitcoin recipient

Hi I sent a slightly lower amount than what I should have sent to the bitcoin address. The TXID appears in the blockchain as unconfirmed. Paxful which is the market place I used, say the payment is pending. I have contacted their support but awaiting a reply.
I'm just wondering if there's any experienced people here who can help me rectify this.
Cheers

هنگامی که مقداری ارز دیجیتال را از کیف پول خودتان به کیف پول دیگری انتقال می دهید، جزئیات انتقال (مقدار ارسالی، ارسال / دریافت، و همچنین تاریخ انتقال)را می توان در بلاکچین یافت. این اطلاعات سپس در دسترس خودتان قرار می‌گیرد و به صورت ID تراکنش و یا TXID برای شما نمایش داده می شود.
چرا الزامی است که #TXID حتما در فاکتور فروش به ارزینجا ثبت شود؟
TXID به منزله شناسه واریزی انجام شده است و به طور معمول تایید می کند که این مبلغ را با موفقیت ارسال کرده‌اید یا خیر.
چگونگی پیدا کردن TXID در شبکه بلاکچین:
از آنجا که فعالیت بلاکچین برای اغلب ارز های دیجیتال در دسترس است، چندین وب سایت مختلف وجود دارد که می‌توانند برای شما راهی برای کشف TXID فراهم کنند.

Electrum unable to sign transaction properly

I'm new to using bitcoin and I'm trying to figure out a problem I've been having trying to broadcast a transaction with Electrum. Initially I was trying to send bitcoin using Electrum's built in "send" function, but kept receiving the error "scriptpubkey." After browsing other forums and seeing issues similar to what I was having, it seemed like people were saying that it was an issue with the server I was connected to. In some cases, people had to try 15-20 different servers before finally being able to send the transaction through.
I thought this was the probable cause of my situation as well so tried about 20 different servers but to no avail. Then I read about "pushing the raw hex transaction" (not sure if I am using the right lingo here) and decided to try that. I was able to make an offline transaction with Electrum and signed it, then obtained the hex code from the .txn file that was created.
I then tried to broadcast the hex code on blockchain.com/btc/pushtx, but I am still receiving the error " Code: -26, Error: scriptpubkey."
So after doing some more research it seems that my problem now is not that there was an issue with servers in Eluctrum, but rather my transactions are not being properly signed. So now I have a signed offline transaction that seems to be improperly signed by Electrum, and I am clueless as to how to correct this.
Is there a way to "unsign" the transaction and sign it again properly? How would I even go about doing that? I fear that I now have money locked up in this faulty transaction that I may not be able to recover. I have all my passwords and everything so I am confused why Electrum would not have signed it properly. I am very new to all this so I'm sure I could be missing something essential. Any advice on how to broadcast and complete my transaction would be much appreciated.
I am running the latest version of Electrum on a Windows 10 computer.

Thanks!
Edit: Latest version of Electrum being 4.0.2
Also, I suppose it is probably helpful to see the decoded transaction here:

Sent mistakenly 1 BTC to Huobi's cold, please help me to contact CEO (+1 year unresolved)

Hi everyone, 19 months ago I sent mistakenly 1 BTC to the Huobi's cold wallet. Yes, I'm retard, I feel terrible.
Transaction:
https://www.blockchain.com/es/btc/tx/4769c93d8c9e0d5eaf8311ac8af513e23096ae461da0256a77cf70ca73fd4e4b

How I send mistakenly 1 BTC to the Huobi Cold Wallet?
A day I was watching a BTC rich list and exploring the addresses. I'm unsure how exactly it happens because I verified the address, but when I sent 1 BTC I did mistakenly to the wrong address!!! I verified that I was sending to the correct address, but I had to remake the sendship because the wallet crashed, probably there was the problem, the huobi's cold wallet address was in the clipboard. Anyways I don't have certainty how it happens.List: https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html
It was a mistake, I work often sending and receiving BTC. When you do a certain task all the days copying wrong data could be a TERRIBLE but EASY mistake to do, because we are humans and we fall in the trust. As you did a task correctly many many times you earn trust on yourself and try save time. If it didn't happens to you ever you aren't being honest.

7 months talking with Huobi Customer Support (part 1)
I tried to contact Huobi's customer support. First they first didn't understand me, thinking that I tried to deposit on Huobi and sent to a wrong address. After they understand they told me that the address doesn't belongs to Huobi and they can't help me. That is false, I did an investigation and they have direct relation with this address, they can help me. Read my following analysis please:

Huobi Ownership Analysis
Searching, sites says that the address belongs to Huobi Huobi support says that address doesn't belongs to Huobi
I don't know if belongs to Huobi or not, but I can deduct and track that the address is related with Huobi
Why? The address 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 regulary sent big amounts to 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D
Then, is VERY PROBABLY THAT 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 OWNER KNOWS 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER And the 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER can help me.
Searching, some sites (and sites like USDT Official page https://web.archive.org/web/20181113185656/https://wallet.tether.to/richlist) says that the address 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D belongs to Huobi
Again, I don't know really if the address is of Huobi, but I can deduct and track that the address is related with Huobi
Why? On my Huobi account I made only 2 BTC withdraws from Huobi in the past
2018-05-08 18:36:45 , txid: 0e6bf02323ebc166b6638afcd6170ecb73948748235e687def7e7a3cb1902fca , it has 239 inputs 2018-05-08 20:17:10 , txid: b59b988d642fe3773268e246ef1a0d048bbd3f734a611d00722b39126ed9e20b , it has 239 inputs too
In both transaction, all inputs are addresses that BELONGS TO HUOBI, because you huobi are sending me BTC
Both transactions has 39 addresses as inputs in common (all huobi address, maybe deposit addresses of anothers huobi users)
Example: 1M9ndPSQ4fmMKaKW2oX7LtjduDqYUcFKCW
Analyzing the transactions of this address, we can found many transactions sending BTC to 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER
https://www.blockchain.com/es/btc/tx/740236113bde5a95cfc168d732762be00eee435556c686b00b74b85b3e6c3f77https://www.blockchain.com/es/btc/tx/e2367daa464818d46da93e9a364f23536ef31e767f04cd01ff0a01e2baca6f87https://www.blockchain.com/es/btc/tx/5c16244c0efaba9aeb1e141e9ff4c8702f7a34f44bac73121ea6f55eb98adab2https://www.blockchain.com/es/btc/tx/69e73d1bbcdcb8ffacf0ea555298ee226f1740c02d1131e2db72e7ade32aace1https://www.blockchain.com/es/btc/tx/110eff2733a88b626ca38d63b9f2d8b6d5b3e26574f1d918c99c36c785eb0d56
User withdraw? No BECAUSE the amounts are lower than the quantity required for a Huobi withdraw (0.01 BTC) VERY VERY PROBABLY that 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER is Huobi And seeing all transactions, probably all of them are being used to pay USDT fees (i didn't study this part but isn't relevant)
Then, if 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER is Huobi, you can help me High probably that you know the 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 OWNER , address which I mistakenly sent 1 BTC
Please, tell him that give me back my 1 BTC
See my transactions asking the 3CBq.. owner give my BTC back: https://www.blockchain.com/es/btc/tx/d60eed9b025f9c5d3fe3b168e2f64e0abcb880123c1c0a51290eaeddbd60b8d7https://www.blockchain.com/es/btc/tx/0015646c3df821b035a15837b26c65f458276c05128bbaeae3293284d178d14e
sending to 1SentYou1BtcP1sBackToMeP1sNznQ1zH(read the address) and to 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 with the same addresses used to send 1 BTC to 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64

7 months talking with Huobi Customer Support (part 2)
After understanding this , they asked me my consent to pay a fee. I agreed. After they asked me sign a message with my privates keys. I did it. And finally they tell me "Wait". I'm waiting 7 months ago, all months I ask and they ever reply the same "We will contact you". Now they told me " Hello,sorry for the inconvenience, we feedback your problem to our technology department. After a series of research and development, but it can not be solved. Please understand this. "
I want to think that the team is failing and Huobi isn't wanting steal my BTC. What they are doing maybe could be illegal. I'm thinking to talk with lawers on Singapore, I don't know what more to do.
I tried to contact the CEO Livio on Twitter ( https://twitter.com/livio_huobi ) but they don't reply me! I want to think that someone else is administering their account.

Bitcoins sent to electrum from Coinbase haven’t shown up at all.

Basically the title, electrum hasn’t even registered the coins as unconfirmed, there’s just nothing there. Any ideas?

How Do Bitcoin Transactions Work?

Now that you’ve set up your bitcoin wallet and are ready to make your first transaction, let’s take a look at how bitcoin transactions actually work.
There are three key variables in any bitcoin transaction: an amount, an input and an output. An input is the address from which the money is sent, and an output is the address that receives the funds. Since a wallet can contain several input addresses, you can send money from one or more inputs to one or more outputs. There is also a data storage portion on each transaction, a sort of note, that allows you to record data to the blockchain immutably.
But the unique thing about bitcoin transactions is that, if you initiate a transaction that’s worth less than the total amount in your input, you get your change back not to your original output, but through a new third address in your control. This means your wallet typically ends up containing multiple addresses, and you can pull funds from these addresses to make future transactions.
You’ve learned how to buy and store your bitcoins, so you already know what public and private keys are for, and you’ll need these to issue a transaction. To do that, you put your private key, the amount of bitcoins you want to send and the output address into the bitcoin software on your computer or smartphone.
Then the program generates a signature made from your private key to announce this transaction to the network for validation. The network needs to confirm that you own the bitcoin being transferred and that you haven’t spent it by checking all previous transactions which are public on the ledger. Once the bitcoin program verifies that indeed your private key corresponds to the provided public key (without knowing what your private key is), your transaction is confirmed.
This transaction is now included in a “block” which gets attached to the previous block to be added to the blockchain. Every transaction in the blockchain is tied to a unique identifier called a transaction hash (txid), which looks like a 64-character string of random letters and numbers. You can track a particular transaction by typing this txid in the search bar on the blockchain explorer.
Transactions can’t be undone or tampered with, because it would mean re-doing all the blocks that came after. This process is not instantaneous. Because the bitcoin blockchain is fairly large, it takes a lot of time to process a single transaction among the many on the blockchain.
The amount of time it takes to confirm a transaction varies, ranging anywhere from a few minutes to a couple days, based on traffic on the blockchain and the size of your transaction. Larger transactions with higher fees tend to get validated by miners quicker than smaller ones. That said, once it is confirmed, it is immutably recorded forever.
If you want to indulge in some mindless fascination, you can sit at your desk and watch bitcoin transactions float by. Blockchain.info is good for this, but try BitBonkers if you want a hypnotically fun version.

0.5 Bitcoin deposit with 11 confirmations marked as "Pending"

I will update when the date when the 0.5 BTC has been credited. The txid is: https://blockstream.info/tx/837d80a60325ed368553abe3469aa124aabb5e805d851949e0ea1db60c90a415 (Thanks for using Blockstream and not those clowns at Blockchain.com)
No problems with other deposits (0.02, 0.11, 0.12).
Thanks!!! Super awesome seeing such a large platform support Bitcoin!!!
I will update this thread with the results.
EDIT: The Bitcoin transaction was rejected on 5/26/2020. No reason specified and her account was not banned. She was required to scan a QR code in order to have the Bitcoin refunded. She was refunded 0.49981864 BTC on txid: bcac73d996ba35b8ea45f07e6439412a0f60c87b1517cc8aec60a1bf8dc5c962

Calculate txn_id from raw txn_hex

I'm trying to calculate a txn_id from raw txn_hex. The procedure works fine for legacy TXNs but gets non-expected results on Segwit TXNs. I compared this snippet of code to what txn_id was produced by Electrum and the blockchain.com TXN decoder:
  1. Take in TXN in hex
  2. Convert the hex to binarray
  3. Double hash binarray
  4. Reverse the resultant digest because of endianness
  5. Display in hex.
t0 is my legacy testnet TXN and t1 is my segwit testnet TXN.
Thoughts?

UPDATE

Found the relevant source in Electrum transaction.py:1036
Basically you strip the flags and tx_witnesses listed in the wiki spec

How do I trace/prove that I sent BTC to a recipient?

I'm going to be very concrete here, so nothing is lost. I needed to send 0.00149759 Bitcoin (BTC) to the address 1Jn5WnoGe9wY9et57ifTCqD3YnfoXyqMmf
So in my Waves.Exchange app, I sent that.
And you can see at the target address that the amount was received at 2020-04-02 5:47:48.
But that does not prove that I sent it: * nothing in the Waves.Exchange app withdrawal transaction has the ultimate recipient address. So a screenshot of my completed transaction only proves I sent it to some gateway * When I click on the txid in the Waves.Exchange app it takes me to a transaction but there is nothing about this Waves txid to link it to the received txid on the bitcoin side ... so anyone could claim they sent the BTC instead of me.

Sent mistakenly 1 BTC to Huobi's cold, please help me to contact CEO (7 months!!)

Hi everyone, 7 months ago I sent mistakenly 1 BTC to the Huobi's cold wallet. Yes, I'm retard, I feel terrible.

Transaction:
https://www.blockchain.com/es/btc/tx/4769c93d8c9e0d5eaf8311ac8af513e23096ae461da0256a77cf70ca73fd4e4b

How I send mistakenly 1 BTC to the Huobi Cold Wallet?
A day I was watching a BTC rich list and exploring the addresses. I'm unsure how exactly it happens because I verified the address, but when I sent 1 BTC I did mistakenly to the wrong address!!! I verified that I was sending to the correct address, but I had to remake the sendship because the wallet crashed, probably there was the problem, the huobi's cold wallet address was in the clipboard. Anyways I don't have certainty how it happens.List: https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html
It was a mistake, I work often sending and receiving BTC. When you do a certain task all the days copying wrong data could be a TERRIBLE but EASY mistake to do, because we are humans and we fall in the trust. As you did a task correctly many many times you earn trust on yourself and try save time. If it didn't happens to you ever you aren't being honest.

7 months talking with Huobi Customer Support (part 1)
I tried to contact Huobi's customer support. First they first didn't understand me, thinking that I tried to deposit on Huobi and sent to a wrong address. After they understand they told me that the address doesn't belongs to Huobi and they can't help me. That is false, I did an investigation and they have direct relation with this address, they can help me. Read my following analysis please:

Huobi Ownership Analysis
Searching, sites says that the address belongs to Huobi Huobi support says that address doesn't belongs to Huobi
I don't know if belongs to Huobi or not, but I can deduct and track that the address is related with Huobi
Why? The address 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 regulary sent big amounts to 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D
Then, is VERY PROBABLY THAT 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 OWNER KNOWS 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER And the 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER can help me.
Searching, some sites (and sites like USDT Official page https://web.archive.org/web/20181113185656/https://wallet.tether.to/richlist) says that the address 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D belongs to Huobi
Again, I don't know really if the address is of Huobi, but I can deduct and track that the address is related with Huobi
Why? On my Huobi account I made only 2 BTC withdraws from Huobi in the past
2018-05-08 18:36:45 , txid: 0e6bf02323ebc166b6638afcd6170ecb73948748235e687def7e7a3cb1902fca , it has 239 inputs 2018-05-08 20:17:10 , txid: b59b988d642fe3773268e246ef1a0d048bbd3f734a611d00722b39126ed9e20b , it has 239 inputs too
In both transaction, all inputs are addresses that BELONGS TO HUOBI, because you huobi are sending me BTC
Both transactions has 39 addresses as inputs in common (all huobi address, maybe deposit addresses of anothers huobi users)
Example: 1M9ndPSQ4fmMKaKW2oX7LtjduDqYUcFKCW
Analyzing the transactions of this address, we can found many transactions sending BTC to 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER
https://www.blockchain.com/es/btc/tx/740236113bde5a95cfc168d732762be00eee435556c686b00b74b85b3e6c3f77https://www.blockchain.com/es/btc/tx/e2367daa464818d46da93e9a364f23536ef31e767f04cd01ff0a01e2baca6f87https://www.blockchain.com/es/btc/tx/5c16244c0efaba9aeb1e141e9ff4c8702f7a34f44bac73121ea6f55eb98adab2https://www.blockchain.com/es/btc/tx/69e73d1bbcdcb8ffacf0ea555298ee226f1740c02d1131e2db72e7ade32aace1https://www.blockchain.com/es/btc/tx/110eff2733a88b626ca38d63b9f2d8b6d5b3e26574f1d918c99c36c785eb0d56
User withdraw? No BECAUSE the amounts are lower than the quantity required for a Huobi withdraw (0.01 BTC) VERY VERY PROBABLY that 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER is Huobi And seeing all transactions, probably all of them are being used to pay USDT fees (i didn't study this part but isn't relevant)
Then, if 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER is Huobi, you can help me High probably that you know the 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 OWNER , address which I mistakenly sent 1 BTC
Please, tell him that give me back my 1 BTC
See my transactions asking the 3CBq.. owner give my BTC back: https://www.blockchain.com/es/btc/tx/d60eed9b025f9c5d3fe3b168e2f64e0abcb880123c1c0a51290eaeddbd60b8d7https://www.blockchain.com/es/btc/tx/0015646c3df821b035a15837b26c65f458276c05128bbaeae3293284d178d14e
sending to 1SentYou1BtcP1sBackToMeP1sNznQ1zH(read the address) and to 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 with the same addresses used to send 1 BTC to 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64

7 months talking with Huobi Customer Support (part 2)
After understanding this , they asked me my consent to pay a fee. I agreed. After they asked me sign a message with my privates keys. I did it. And finally they tell me "Wait". I'm waiting 7 months ago, all months I ask and they ever reply the same "We will contact you". Now they told me " Hello,sorry for the inconvenience, we feedback your problem to our technology department. After a series of research and development, but it can not be solved. Please understand this. "
I want to think that the team is failing and Huobi isn't wanting steal my BTC. What they are doing maybe could be illegal. I'm thinking to talk with lawers on Singapore, I don't know what more to do.
I tried to contact the CEO Livio on Twitter ( https://twitter.com/livio_huobi ) but they don't reply me! I want to think that someone else is administering their account.

My ownership evidence:
Message:
