I believe Fold App/Card is not a great product for its target customer base. Yes you get free spins & gain some sats but in order to get 1% back on purchases in sats you pay $10/mo. To break even you would need to spend $1000/mo & the issue is Fold is a prepaid debit card. Who spends $1000 or more a month on a prepaid debit card? Why not take the $10 and just spot buy which would get you about 35k sats at a $28k BTC price.
