Not anymore, we don't. Steem effectively fixed that. Now rather than submitting yourself to a criminal interrogation and week-long delay while they get past the guilty until proven innocent stage, people can just start earning Steem and trade to BTC or any other crypto from there.
The mainstream is not going to suddenly start going through Coinbase (which treats them like criminals) to buy BTC with their hard-earned fiat. They aren't going to spend a cent on it, much less waste hours and days of their lives doing absurd verification procedures. I do blockchains professionally and I won't go through those absurd verification procedures (admittedly for a much different reason). But when people can post on social media, get paid in crypto, then trade that crypto on an altcoin exchange (which treats them like a customer), and buy something on Amazon with it (thanks, Purse.io, for not going darkside), then you've created an experience a soccer mom can handle.
I just think non crypto folks are more likely to go through coinbase than to trade on an altcoin exchange.
