i mean usable for POS... you can't be waiting much longer than a visa/MC card payment or it's not gonna fly

can't do that with stables, only Lightning, and the only well developed ecosystem for this tech is bitcoin lightning

also, stablecoins are already at peak demand at this point... xapo bank supports USDC and USDT as well as onchain and lightning BTC, but you simply can't do POS with stables, just can't

the payment use case is important... only bitcoin has the tech that can take Visa/MC/etc out of the loop which makes it much more viable for physical retail/hospitality
