If bittrex or binance got hacked that's not my problem, this statistics also 100% shows how garbage their security system is (behind this security system there are IT personals which seems can't do their job properly). People usually use bitcoin for two reason: 1. Privacy 2. Profit, so when privacy is my choice, I think KYC documents must be far away from it. And if fraud happens because of stupid user, that's another task.
