This was my immediate question. I bought some Etherium from Coinbase a couple weeks back and by the time I got the funds, the value had dropped (!)25%. I don't particularly care because I'm long on my crypto holdings, but in what world is something like that going to be tolerable for merchants?

It sucks, but you can store cash there in advance, and purchase on the fly when desired.
