Crypto-only is the design constraint that separates operators who built around blockchain rails from operators who added a USDT deposit method to a fiat-first cashier. The difference shows up in withdrawal speed, network options, and how the cashier handles a chain switch.
This list ranks operators that do not accept fiat at all. We weight number of supported cryptos and the broader rating. Brands that built crypto-first usually offer Lightning, deeper altcoin coverage, and faster cashier flows than fiat-first operators that bolted on a wallet.
The trade-off: no fiat means no banking partner risk on your end. It also means no chargebacks, no banking ombudsman, and no fiat exit route if a withdrawal stalls. Crypto-only is faster on the upside and harder on the downside. Plan accordingly.
