Pretty sure crypto will be the new widespread financial system.. Global financial system is questionable though.. It seems more like there will be two or three large ones warrring against each other for control of commerce, kinda like Binance vs Coinbase type stuff.
USDC vs BTC, XRP vs DAI.. Could be something like that. Market cap wars too.
And then the sanctions.. Like... Imagine blocking USDC access to entire continents. Like XRP in the states..
