That's still money, it's just different currencies. Money (or currency) is something that is widely accepted to have value not from its inherent properties but because it is accepted everywhere in a transaction. If something is difficult to exchange quickly with most exchange partners (e.g. taking days to transfer stocks from you to a gas station) then it's either not a currency or its a bad currency. Bitcoin and other cryptocoins are "sort-of-currencies" because you can't practically use bitcoin and stop using USD. This is why the SEC is starting to treat crypto like a security.
