Agreeing with @dkbit98, security/secret questions are ineffective as they tend to be easier to uncover.

One, the questions can be as basic as something ppl can get thru your social networking account e.g. which high school did you go to?
Two, the questions can be seen as trivial hence ppl feel less threat in answering them and makes social engineering easier.
Three, seeing the question narrows down which words to try

Security wise, it's better to remove this feature and just stick with the mnemonic seed being the only way to access the wallet if password is forgotten.

I'd say keep doing one and two first, who knows you might gather enough attention for coinbase to return your funds or might trigger a group of people to start a class action suit on them for this.

Some tips to improve ppl's engagement on your posts:
First is post proofs, this is so ppl can trust your words and further strengthen your case.
Second is a detailed sequence of what happened-- self explanatory
Third is a catchy title like a short tl;dr for platforms like reddit or this, the goal is to make them stop from scrolling.

Speaking of class actions, I found something that intrigued me in silvermiller firm--they're looking into coinbase's suspicious practices, though not the exact same case as op, it is similar enough.

Ignoring the barbaric last post, op's concerns are valid since you need the private keys to recover the coins, and only coinbase has access to it. Assuming this is what it is, it could either be a case of an inside job or just a shady move from coinbase where they straight up refuse a cross-chain sent recovery request only to do it at a later time when most have forgotten about it and without any intention of giving it back 🤔

What you can do is one, continue to pester their support. Two, attract ppl's attention by making a noise in other communities, urge users who had a similar problem to check their cross-chain sent coins if it move. Last is to explore legal options but that depends if the amount is worth it. also, are you perhaps from USA?

You can ask them to terminate your account along with your data sets. Binance is gdpr compliant which gives users data protection rights (check their privacy policy under section eight).

The tricky part is the data retention which allows them to keep some data for X amount of years, better to also ask them what happens if you change your mind and open an account again in that period of time just to make sure it wont get you in trouble.

If you're still having a problem, try to reverify in your new account. Custodial wallets like trading and interest are tied to your identity profile and therefore should show up once you reverify. Just pray you wont trigger their manual verification as that can take days or weeks.

@annerl, are you trying to claim your ETC from the fork? then rest assured because a replay protection has been implemented on ETH's side (not sure about ETC), so just send your ETH first and your ETCs are good to go. Also, make sure you are using the latest version and not a fake phishing wallet.


It's quite alarming that the support doesn't know ETC is on a separate blockchain, it's a very basic info and it sheds light on how their employees are screened/picked...

Certainly not the first time they have tried this. At this point, it's safe to say that the past endeavors were successful enough for them to do it again otherwise they wouldn't waste manpower. With how quick ppl are in devaluing their info, it'll be bad if this spreads and other exchanges try a similar thing.

Not that i agree with their method, but it's actually good even for those at the top to not be relaxed and always try new things to improve their platform/service.

Bithumb global is a separate entity from bithumb.com (the south korea one) and therefore has never been hacked, although i do understand the skepticism about it as they share the same name and have some sort of connection.

@op, what you can do now is to go around the internet and spread the word hoping you get enough attention for them to prioritize you 

Maybe op confused sent with import?

It looks like they originally had a legacy wallet (16 word phrase and 2013), so it could be that their account was upgraded to use the current HD wallet and so the funds (the keys) from their legacy wallet is now in 'imported addresses'. You can check this @op if you have a way to compare your legacy wallet addresses to the ones in 'imported addresses'


Does this happen in every browser/device/internet connection? If so, since when? perhaps since the transition which happened in q1 of 2016?

Before you could see it? does that mean you didn't manage to save it? then it's a lost case. It's their non-custodial wallet so it means even coinbase has no access to your funds, hence won't be able to help you.

It's a different case if you saved in a text file or something, you can try to see if a data recovery software would work. Also if your file manager has the recycle bin enabled since some of them has it enabled by default.

Just to clear it up, what happened was it used to be a 7-day period


then blockchain.com shortened it to 3 days which is now what we are seeing in the live article.


@op, did you buy using your card? then reach out to their support if three days has passed and the problem still persist. I'd escalate it thru their twitter too (https://twitter.com/AskBlockchain)

It seems to be a problem on their end.

Check their telegram (https://t.me/EN_HitBTC) and look up the word 'doge' you'll see lots of ppl having withdrawal problem. First ones who expressed complaints were in the same day op posted this. After some time hitbtc closed the withdrawals


but is now open again although it's still not in its best condition.



Get in touch with their support op, if you still haven't withdrawn your funds.

Looks like it works similarly to blockchain.com where they store the encrypted wallet file in their servers so users are able to access their wallet with just an email and password using a browser in any device, while also giving them a discounted non-custodial experience. Discounted because of the unknown part of how those wallet files are being kept and that encrypted or not, it's a lot better to not have your keys lying around somewhere.

Was the transaction initiated by the hacker already with confirmation/s when you found it?

The hacker doesn't seem to have an access to your custodial accounts seeing that they can't move the funds themselves. It can't be the holding period either since you were able to withdraw. Waiting on what the support can do for you may be the best for now. Reach out to their other channels too like twitter (https://twitter.com/AskBlockchain).

I'd ask them about the first method i mentioned in my previous post too which is recovering your interest account in a newly created blockchain.com account-- you wont be using the compromised backup phrase.

Your blockchain.com wallet is linked to your custodials so that may pose a problem for you like triggering their suspicious flag if the wallet + identity profile must go as a set.

If there are signs that funds from your interest account are still safe there are two methods i could think of to try.


It does say the interest account is tied to your identity profile so maybe even if you verify a freshly made blockchain.com account, funds would still show up? However there is a chance you might trigger their flags and get your funds locked but hey it's better to deal with their support.

or..
Recovering your account thru blockchain.com does gives you a new wallet ID and such so it's pretty much a new shell/account but same wallet, maybe youll be able to access it fine this time. The hard part is because the wallet is already compromised it becomes a race between you and the hacker on which transaction gets to be confirmed first. After you send the bitcoins to your compromised blockchain.com wallet go to electrum and do this (https://bitcoinelectrum.com/how-to-do-a-manual-child-pays-for-parent-transaction/). The higher miner fee you put, the faster it would be to be picked up by a miner. I consider electrum's fee estimation to be reliable, try to set it to "mempool" and target .5MB or less.

This all assuming they won't redirect you to manual verification which could take weeks...

If your friend is still having a problem accessing their funds, try to recover it using btc.com's recovery tool (https://help.btc.com/hc/en-us/articles/115003783333-How-do-I-recover-my-wallet-using-the-backup-PDF-). and yes they need their backup pdf for this. BTC.com forces their users to save the file so they probably have saved it. The problem is finding it (https://help.btc.com/hc/en-us/articles/360002937174-I-have-lost-my-backup-PDF-where-could-it-be-)

If the recovery tool weren't able to detect the mentioned address, then it is not from that account. They can contact the support and see if they can provide further confirmation/info.

They had some connectivity issues around the time you posted this. According from their status page, a fix has been made. I tried logging in thru their website and it all went fine, should probably work on your end too.



Their status page (status.coinbase.com) is also another way to check coinbase's condition aside from their SNS.

afaik the mnemonic in blockchain.info back then was only used for recovering passwords and doesn't contain any keys.

do you recall saving a json wallet file or paper backup? try to look for them. See this old article for reference: Tutorial: Backup Basics! The Best Ways to Backup Your Blockchain Wallet. Users also had an option to save them in clouds like dropbox and gdrive.

Website is back now and according from them, it was just maintenance.



I see this unannounced maintenance happening again so better bookmark their other domains too @op. Reading the past messages in telegram, it seems the other domain(s) were working while gate.io was still down.



Go to their telegram and search for "domain", afterwards verify them thru https://www.gate.io/en/officialverify while it is up and running. It's a cool feature but they should've put it in a standalone platform.

When that happens, you can also try searching in their other social channels like twitter, telegram etc.. bc there's always a fair chance that someone has asked the same thing especially when it comes to basic questions. and yeah since no one was sure, here:



as for the withdrawal fee, op can pretty much trust what the article says (which noorman0 linked) since it's from the exchange itself. It's very weird that you have to ask for such info tho, cause the standard is for it to be displayed in the withdrawal section and their support articles.
