People who make enough money to save 20% of their deposits probably aren’t going to bother with some convoluted system to earn a maximum of $3000 interest annually. You could make more with AMEX points.
You make amex points if you spend money. I barely spend anything I make (and whatever I spend mostly can't be on cards) so for people like me this will be ideal. Given the pandemic and wfh boom I doubt I'm alone. I'm also extremely averse to every speculative investment bin right now, so if someone guarantees coverage for 3% inflation I'll happily give them my money.
That just means people with six figure savings won't use the service, it's still not clear how that helps them achieve profitability with such high interest rates
