crypto-only vs card checkout: what each one costs you

a card checkout costs the seller roughly 2.9% plus a flat fee per transaction, and it costs you the right to reverse the payment if something goes wrong. that second part is the one people forget, because it doesn't show up as a line item. it shows up six weeks later, if a parcel never arrives and you call your bank instead of the shop.

a crypto-only checkout costs you a network fee, usually a few cents to a few dollars depending on the chain, and it costs you that same right to reverse anything. once a transaction confirms, there is no bank standing between you and the seller to claw the money back. you are dealing with the seller directly, for better and worse.

what a card actually costs

the 2.9%-ish processor fee is the visible part, and it's paid by the merchant, not you — though it's baked into retail prices everywhere, so everyone pays it eventually, just invisibly. the less visible part is currency conversion: if the shop bills in a currency your card doesn't hold, your bank often adds another 1-3% on top, silently, at whatever rate it feels like using that day. and the real cost is procedural: a chargeback dispute can take weeks to resolve, during which the seller's funds are frozen and the shop has to prove the order shipped, the size was right, the description was accurate. that machinery is why most processors won't work with a one-person studio selling one item at a time — the dispute overhead costs more than the sale.

what crypto actually costs

network fees vary enormously by chain and by the minute. sending usdt on a congested chain can cost more than the fee difference a card would have charged; sending it on a cheaper network can cost a fraction of a cent. that volatility in fees is itself a cost — you don't always know what you'll pay until you're about to send it. the bigger cost is structural: there is no dispute process. if a seller takes payment and never ships, there's no institution to call. your recourse is the seller's reputation, a public order history if the shop keeps one, and whatever goodwill exists between you. that's a real cost, and it's worth pricing in before you buy anything that way.

there's a second, quieter cost on the crypto side: timing risk. between clicking buy and the transaction confirming, the value of what you're sending can move. on a stablecoin like usdt this barely matters. on eth or btc priced in the coin itself rather than pegged to a currency, it can mean paying meaningfully more or less than the sticker price by the time it clears.

who actually pays, and when

with a card, the cost is spread thin and paid upfront, by everyone, whether or not anything ever goes wrong — that's what the processor fee is for. with crypto, the cost is concentrated and conditional: near zero if the transaction is routine, potentially total if the seller turns out not to be trustworthy. a card is insurance you pay for on every purchase. crypto is a bet that you won't need insurance this time.

neither is wrong. a shop that ships fast, communicates, and has a track record makes the crypto trade an easy one — lower fees, no chargeback overhead on either side. a shop you've never heard of, paid upfront, with no way to reverse it, is a different calculation, and it's fair to decide it's not worth it. we take payment this way at little bit seoul because it's one maker, one item, and the fee overhead of card processing doesn't make sense at that scale — but that's a reason for us, not a reason for you. check who you're paying before you check how.
