Polymarket uses open orderbooks where you match against someone else who wants the other side of the trade just like the stock market. Prices are set by the market, as they should be.
Nobody should be day trading unless it's their job. Yes, I have seen many guys get sucked into it.
While we're at it, I propose a Board of Ethically Allowed Activities that make sure we can only do the good and moral things.
The difference is that hobbies are fun. Gambling is fun in the same way smoking is fun. It's not, but you have to do it. I know, because I was a smoker.
Also, on the topic of morality: morality is stupid. Gambling isn't immoral. Or maybe it is, I don't care. Gambling is self destructive. It can pretty much exclusively only make your life worse.
