in 2017, coinbase watched as endless waves of investors bought into BTC through coinbase but immediately sent all their coins to poloniex, bittrex, and binance to trade shitcoins. i almost felt bad for them. they were vital to the ecosystem and they paid through the nose on AML compliance, but shitcoin exchanges who didn't even require KYC were raking in all the dough.
they obviously don't intend on letting that happen again. they know (as well as i do) that altcoins will go crazy again in the next bubble, and they are positioning themselves accordingly. in april 2017, coinbase only had BTC and ETH listed. now they have dozens of shitcoins, something like ~60 markets in all, and more to come i'm sure.
their shareholders value profits over loyalty to bitcoin. no surprise there. it's just business.
I think that's fair enough but it's ever so slightly disingenuous of him to pretend that all the shit they're touting is somehow vying for the crown. And it is more than business for him in particular. I can't think of many other bigwigs who pussy out at remarking on reality.
Maybe that's how you get people through the door but if it were me I would remain neutral at best and acknowledge Bitcoin's position.
