> If you're using it as a currency then you're not holding it for significant periods of time and the entire point is to make it an automated process, so you're buying some cryptocurrency for cash and then immediately spending it. How much volatility do you really expect in the timespan of a fraction of a second? That is the point of me mentioning that points 2 and 3 are linked. If you are only immediately purchasing crypto and then using it for a purchase, your middleman risk has moved from the payment processor to the crypto exchange. Every purchase you make now relies on whether or not you can make the exchange at the moment. Which is point 3. The alternative is you make larger exchanges of money, which means you need to deal with volatility: point 2. If the price of crypto was stable (at least about as much as any major currency), you could exchange much of it in bulk, and delays in exchanging it back into cash would be less of an issue. Even less of an issue if more merchants accepted crypto: point 1.
