Do you reckon he has the slightest point or is it the hopeless ramblings of someone who wants you buy as many shitcoins off him as possible and wees himself in the face of the one project immune to his power?
as a bitcoiner, i don't take it personally.
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.
