I'm not sure if it's true. I withdrew just about 0.8BTC last year and they were holding my withdrawal until I can submit my documents and a video. The KYC verification for all exchanges is mandatory even for an account holding less than 1BTC. This is a regulated market already, and everyone had to undergo the critical examination.
This is strange, I made a withdrawal a few weeks ago (not as big as
BTC0.8 to be honest) and they didn't ask me anything. AFAIK the rule of the daily
BTC2 is still in force. Another thing would be that this rule is changed whenever they want without previous notice, so it is a good advise to never have too much money in any exchanges.
BTW, anyone knows whether KYC is mandatory in Huobi Global? I hardly ever read anything about this exchange, abut my impression about it was quite good when I used it in the past.
