If crypto debit cards exist, as that item indicates they do, and merchants rely that your card debits crypto from your holdings and the merchant gets fiat money on account from the intermediary, then it seems crypto has a better basis than if you could only trade between different crypto tokens and then use Binance to withdraw dollars, each time paying a transaction fee, then there is more motive to delve in crypto, for as long as Binance remains solvent and is better run than FTX was.
There will always be a transaction fee, with that being how the debit card provider makes money, so the game is to gamble on whether crypto will build in value, or drop; with some such as Luna having crashed entirely rather than fluctuated with volatility but within a band of values; then it is just another higher risk casino than using a stock broker and/investment adviser, the latter being good because she can play the range of markets better than you, as an amateur.
Or move to El Salvador, where Bitcoin is legal tender.
UPDATE: Living in Ramsey, MN, what merchants would accept a crypto debit card is a question; or say in Alexandria, MN? Visa and Master Card seem trusted. What if you found a good deal on a crypto debit card's transaction fees, and the card provider turned out to be an FTX type of venture going down in flames?
Don't overload the debit card you purchase and keep funded being a caution to consider. Keep it at a modest balance. There is no FDIC assurances on balances held in crypto debit cards.
