Not sure if this counts but I’ve stacked almost 2million sats on my Fold card since May-ish. Not sure how long the great rewards will last with more competitors joining the fold but after spinning a couple of 100% cash backs on groceries I know I’m wayyyy ahead of my 2% cash back cards. Also if you pay estimated federal taxes you can use it to get sats back via debit card (although they recently neutered the limit to $20)
