lol it's not hard. people keep saying this. exchanges process insane volume even when taking into account churn volume. There are hundreds of exchanges. The odds are almost 100% you can process anything.
Monero's Market Cap is 4,2B & Volume was $164M today so... Kinda.
but also, no one moves that kind of money without thousands of microtransactions, plus the arbitrage bots start to feed when there's alot of volume making it more stable than the normal financial system.
