What Strikes Missing
APYs on Bitcoin, and Fiat Balances.
Debit Card
Silent Payment, Coinjoin, or Payjoin withdrawals
Sats Cost Averaging (the ability to buy a set amount of sats on a frequent basis, both Coinbase, & Kraken offer this).
Maybe a Debit+, or a Buy Now Pay Later system since you’re leaning into credit products it seems, that’s where strike is ahead the most is credit offering.
If I recall correctly you were planning to do credit cards, if you are just make sure they’re reasonable, & not giga fiat.
I will be honest the other Jack has you beat as far as spending Bitcoin P2P.
But credit products might be your edge for now.
