Зашибись, у меня там тоже несколько аккаунтов, правда торгую с одного, остальные использовал для дополнительных адресов, с которых выводил на основной аккаунт.
Можно узнать, на что именно сработала блокировка?
Попытался вывести всю сумму с аккаунта. В их письме сказано, что есть подозрение на использование их сервиса как миксера криптовалюты. Хотя я использовал их как раз по прямому назначению - как обменник - завел одну крипту, продал, купил, попытался вывести другую. Даже анонимную крипту не использовал - никаких monero или zcash.
Бред какой-то. Что-то ты темнишь, парнишка

You have used our platform only to send and receive funds without (yet) hardly using the intended functionality of our platform, i.e exchanging and margin funding / trading. By doing so you have hit a number of possible AML / CTF flags. We see users taking very similar actions but with less honest intentions.
To give you a bit of background on how your activity might be seen as suspicious; we see users set up new accounts, start depositing funds in cryptocurrencies, not use the platform and after a few hours / days withdraw to a different address than the origin address. The goal of this activity is to hide the origin of the funds originally deposited.
Basically, user sends cryptocurrency to Bitfinex address > funds are moved into Bitfinex Hot wallet > withdrawal request to new address > funds are sent from Bitfinex hot wallet to new address. The cryptocurrency withdrawn will no longer be associated to the funds deposited as they will be sent from completely unlinked addresses.
For anyone else but Bitfinex, it would become impossible to follow the funds afterward. Users like this tend to repeat this process across several services adding additional barriers.
If users wish to hide the origin of cryptocurrency assets we have no real objections to that particularly and users can use dedicated mixing services for that if they wish (which is a risky activity in itself as operators of mixing service tend not always to be law abiding citizens themselves...), however we refuse to be actively assisting in his process.
As you may know, we have a few stolen Bitcoins we would like to see returned to us at some point and operating a mixing facility in this way would be a bit counter-productive.
We will need to ask you to provide us with a scan of your current government issued ID and an image of you holding your photo ID to the manage documents section on the verification page. Also, have a reference to Bitfinex and today's date displayed in this last picture - a note with the word "Bitfinex", today's date will do. Make sure your face will be clearly visible and that all passport details are clearly readable.
Вот их письмо. Заметь тут никаких претензий к происхождению крипты или подозрительно большого количества поступлениях (потому что крипта чистая и транзакций пополнений было две).
