How is this different from a debit card? I don't use debit cards. I pay for everything with CCs and pay off the balance when it comes due. Crypto would just charge me instantly. Why do I want that? Yes, it seems more and more stores are charging fees to recover a part of what they pay the CC companies. But you also get nice discounts like discounted gas with the BJs card and 5% back.All fair points, but I'd suggest thinking a little differently at least in terms of where these things operate as of today. Things like Yellow Card, Solana pay, etc. are designed to replace cash transactions as much as they are credit cards. Carry USDC in a wallet, swipe it at a register and it's no different than paying cash. For the merchant the payment settles instantly, no need to wait or to pay an interchange fee.
