Trying to figure out how this would work, the website doesn't really tell you anything.

Are you fronting this money or during the sign up process you have to bridge your phone number with a wallet, maybe you're generating the wallets/tied to this phone # and they have to load it up... it sounds cool/intuitive to use a phone number.

I'd be concerned with theft too like sim jacking though not sure how often that happens.

Are they going to get a text from blockpay saying "you received coin amount".

Yeah... phone #'s interesting but seems like you still have equal difficulty somewhere else unlike old way of scanning QR code/transferring that way.

Also idk how many lay people use crypto or if they have it it's through something like Coinbase/RH/CApp.
