It’s closer to two trillion. But I think 0.1% is a hilarious number to assert is too high a price to pay. How much is skimmed as central banks flow money to citizens? How much is embezzled in corrupt orgs/nations?
Traditional finance puts power in men that don’t even need to hack anything to take far more than 0.1%.
Half of everything would be likely worth it if crypto lives upto even a smidge of it’s true promise.
