I have done some work at crypto exchanges so I am a bit biased.

I would agree that BTC and many assets are a terrible payment method due to poor UX (block time, clunky wallets), speculation, and wild price swings. But crypto in general works well for payments I would say.

Transaction fees have improved significantly where it can be on the order of a few cents per transaction. So yes this is a little high for a $1 candy bar but this is fantastic for a $1,000 watch.

The number of chains and interoperability is a bit of a pain at the moment, but this problem can be resolved by delegating to a payment processor, or simply targetting ETH, the top stablecoins, and BTC which account for the vast majority of the market.

Again I am biased because of my experience, but I could set up a payment gateway for ETH in a few hours using free public nodes at virtually no cost. No business overhead. No agreements with payment processors or card companies. The biggest cost and overhead ends up being accounting, because crypto still has ill defined laws and regulation.
