Robinhood 5% on cash

I opened an account with them a couple months ago, thinking of taking advantage of the 5% interest on cash they were giving for a limited time (it was supposed to be until today) Now, to my surprise, they have extended it indefinitely. Seems like a great place to have emergency money parked. It’s protected up to 22000€ and transfers are instant (I have tried them myself). Is this a too good to be true thing or you guys are also using it to squeeze a little extra from your emergency cash? submitt
