Crypto has roughly $70 billion a day in total transaction volume. Visa's credit/debit processing network by comparison does about $34 billion a day.
(The Visa number is from 2020, I couldn't quickly find a more recent number)

If I make a new cryptocurrency today and announce it is worth 50 trillion-trillion volume and start trading with myself, that doesn't DDoS no bank.
It's a bunch of bros moaning "arbitraaaaaaaage" while trying to rip each other off.
The amount of crypto used for actual goods and services probably amounts to about $3.50 per day.
$3.50 is much less than $34 billion
