You'd think that, wouldn't you, but surprisingly doing payment processing doesn't necessarily involve any fundamental understanding of the nature of currency, how it's backed, Fed operations, how they related to the Treasury.

Elon makes a lot of questionable statements about BTC and currency.

A few weeks ago:

"Having some bitcoin, which is simply a less dumb form of liquidity than cash, is adventurous enough for an S&P 500 company ... When fiat currency has negative real interest, only a fool wouldn’t look elsewhere. Bitcoin is almost as bs as fiat money. The key word is 'almost.'"

His concerns about the funny money nature of the Fed etc. are reasonable - no doubt, but at the same time, almost everything he says about BTC undermines his credibility on those things.

BTC is not a currency or a 'store of value' just because a bunch of people say it is. It's just list of numbers people are trading because they want to. The Fed has problems, but BTC is a populist fiction.
