That is strange because i did a quick google search and i found that exchanges do it
We don't know this,
we don't know why he got his account frozen
we don't know why he don't want to verify his identity
and as far as i know this is a common practice in all exchanges, just an example Binance do this all the time.
And it seems like small exchanges are being forced to implement KYC, Cryptobridge implement it, soon Stex and Crex will also implement, only Coinexchange still on the wild west side.
I was reading this article
https://ambcrypto.com/shapeshift-is-being-forced-to-implement-kyc-aml-policies-says-erik-voorhees/ practically all exchanges are being forced to implement KYC
1. It doesn't matter why he doesn't want to verify his identity.
2. Binance, ShapeShift and all major exchanges have very clear trader levels that they establish... If a trader wants to do more than a certain amount of trading per day, they must upload their KYC documents. Reputable exchanges don't let a trader do what they want and _then_ ask for KYC afterward... They certainly don't block coin withdrawals because of it. If anything, they would be limited to a certain amount of withdrawals per day, not be blocked entirely.
3. We _do_ know that this is a widespread problem for Trade Satoshi and that nobody should be depositing coins there until they clarify the reasons behind what they are doing.
