Ignore the other comments. Its good to have a fiat savings account if you have a family and debt obligations.

I use Capital One savings account. It's 4.3 interest right now. I don't use it a ton because I'm self-employed so I constantly have money moving everywhere all the time.

But I like it because I have my checking, business, and all credit cards with Capital One so its nice to be gaining interest on my savings and I stack a shit ton of credit card points. We just got a $1,200 gift card to Amazon from all of our rewards without paying a dime of interest.
