I trust Blackrock to do business the way they always do business.
People give Blackrock money because they are happy with the service.
Crypto doesn't change anything but people think it does for some reason.
Most of the people I know buying into an ETF are doing it through Fidelity.
Same exact concept though.

People have been trusting Fidelity a long time, but they're just gonna go bankrupt this time around because some paranoid crypto anarchists said so? Not buying it. I also won't put it to the test with my own money or recommend it to anyone else (unless they are my mom who didn't buy BTC at all because I said to put it on a wallet; in that case I just have to be like whatever just use Fidelity).
