People that stacked Coinbase
It makes Bitcoin trading so easy, and Coinbase Pro has the best exchange rates I've seen. The interface is easy to use, the verification is flawless. The only thing missing is a dark theme, but I can live without it.
While I believe the "not your keys not your coins" movement, I def believe I will fail to properly store my keys correctly before CB has a Mt. Gox moment. Risk isn't worth it to own my own keys. CB is still the easiest way for me to buy and hold any crypto.
