You should probably watch this youtube video by finance/economy youtuber PlainBagel, since that covers the information actually pretty directly, including the what-if's about it.
That said, fuck Paypal, hope Paypal gets burned by this and we can rely on this working for no longer having to move money through Musky Husky's dirty blood soaked paws. You can check out the official website here, but as a reminder the way U.S. banking is structured, the Federal Reserve is kind of... an Non-Government Organization? It's complicated.
My current understanding is that people who do business internationally may still be forced through Paypal which holds reliable monopoly in that regard. I suppose we'll see if something like this runs shitty companies like Stripe and Venmo out of business.
Someone with a finance background, plz provide Unpromped Commentary about this kthx
