I think this is a good thing. People should be able to do what they want with their own money.

Not like they couldn't still buy crypto with credit cards. It just made it more of a hassle. You had to buy something with a credit card to trade with someone for crypto.

Though it isn't necessarily smart to bet with money you don't have...but that's actually a feature of various trading platforms. Many allow you to do trades with money you don't actually have, betting that it will go up. It's called leveraging. Only difference is that with this you're buying crypto with credit, hoping it will go up. If it doesn't go up right away, big whoop. You just pay however much you want off the credit card and keep the crypto until it reaches the point where you want to sell.
