BITSTAMP frozen my 10 btc and asking years worth of signed address transactions

[Quidat]

So in short those kind of requirements are just a test if the user would decide to forget those funds that he have? No surprising on any service on this market where
selective scamming or hold-up of funds into some number of users.If they do easily admit and processed out the withdrawals after mentioning some legal aspect then
you cant really avoid not to be suspicious with their modus.

Nah. It's more of fear mongering in the hopes of probably OP stop depositing funds from gambling sites(because most exchanges doesn't like this). If Bitstamp would be to attempt to start such a modus, for a business as big as their size, I'm pretty sure they wouldn't be attempting to grab 10 BTC. If they would attempt to do so, it would definitely be a lot bigger than 10 BTC.

Yeah i got your point which is definitely right and well said, big business like this one will not really risk up to ruin their
reputation for mere amounts of BTC. Dont know why there are still people who arent that careful on sending out their funds
came from gambling sites where most service specially exchangers do have this typical terms or prohibition.
Lesson learned for those who arent fan on reading sites terms until they realize that they already violate when they already
experiencing some withdrawal issues.

Bitstamp has been here for long time and them asking KYC with such strict details does make me wonder what juicy information they have obtained on the coins.

You may try to present a story in your way of describing but this is what I suspect has happened.

No, this is normal for bitstamp, they have been asking similar questions for >5 years now. Other exchanges are catching up with their intrusiveness. It's better to take your time to find a trustworthy person to make an exchange in-person.

No one can be 100% trustworthy. I have seen vendors in Localbitcoins selling their old accounts to scammers and the latter using them to con unsuspecting users. EVen I had a few bad experiences with LBC, and my coins were returned only after I contacted the LBC admins. If you are talking about face-to-face transactions, then they are not only risky, but unsafe as well.

Yes, in-person = face-to-face. Never had a problem, know your surroundings, learn how to spot fakes, and if you live somewhere where violent crime is a concern be armed or bring an armed friend. I'd be more wary of receiving a bank transfer from a hijacked bank account and having my money frozen after releasing bitcoins to the fraudster.

This is insane. I knew that Bitstamp was always overboard with their KYC requests to the point that it's probably even required by law for them to do some of the things that they ask for, but never knew that they would peer into such private details of every single transaction that you make just so that you can withdraw what is rightfully yours.

What right do they have to ask for tax statements, your income, where you got funds from, and what you are going to use funds on? And what relevance does that even have in terms of them upholding a very simple KYC procedure?

Why do they care that this was your gambling winnings? They are not the prosecutors nor the police, they have no proof of any wrongdoing on your side.

Bingo! I see that happen even here on non crypto marketplace sites. The first sign of trust (people think like that) is to avoid new accounts and only deal with older accounts---resulting in scammer offering big money for these older accounts.

People with older accounts who don't often list anything for sale will likely not reject an offer of a few hundred bucks for their account, especially since they can simply create a new one.

It provides scammers easy access to old accounts. By the time people no longer connect trustworthiness to old accounts, scammers will find other routes to gain people's trust and scam them. They are always a step ahead.

i'm not sure on the specifics in other countries, but the USA has strict federal laws prohibiting interstate gambling activity. to avoid liability, banks and payment processors avoid transmitting money on behalf of sportsbooks and gambling sites. this naturally extends to exchanges, which is why coinbase and gemini have policies against usage for gambling in their user agreements. in fact, bitstamp does include something about "illegal gambling operations" in its terms. if the OP were from the USA or a country with similar laws, i wouldn't be surprised to see account termination over it.

and that's what would happen on coinbase or gemini---they would just close his account and send him his funds. leave it to bitstamp to put the OP through hell and possibly steal his coins because he can't prove the source of every satoshi.
