To each his own. 1Broker had amazing UI (better than virtually all crypto exchanges except maybe Bitfinex) and impressive liquidity. And they always acted 100% honorably; impeccable reputation. And they never tried to force KYC on me like so many shitty exchanges that had customer documents hacked. I'm an old school bitcoiner so those things matter a lot more to me than regulatory boot licking and licenses and things like that.
How about eToro? They allow crypto deposits and withdrawals, right?
I'm sure the bigger brokers will eventually get on board, now that the Paypals of the world are entering the fray.
