Don't expect it to last over the longer term and consider how much you'll make assuming you stick to your normal way of banking.
The reason I say this is that there are numerous Fintechs out there doing similar things to entice new customers. One with a high yield (Beam Financial) froze depositor money and it took some time for folks to get their money out (see
https://www.americanbanker.com/news...ct-a-cautionary-tale-for-partners-of-fintechs ). I'm really not sure if it's been resolved, but the company has been in a lot of hot water with regulators. Another Fintech some here are familiar with from a bonus promotion early last year is simple.com. They offered a decent bonus and yield, but it was very awkward - they were pitching their own savings model to "help" customers. By mid-year they were reducing their yield just as quickly as everyone else, and just recently gave up, with parent bank taking control. Another Fintech gave a higher yield depending on how much exercise you did. They've essentially given up as well.
So, for any Fintech, take the time to investigate carefully and try to find what others have to say. I would not expect savings/checking yields above 1% (at this time) to last unless they are making money off of you or your activities...and then you need to consider how much you have to do to get the great yield and/or bonus...or what they are doing to be able to pay you the higher interest rate.
