Polymarket already only accepts cryptocurrencies. :)

Kalshi is worse in a sense that it also accepts fiat payments.

I’d be surprised if there wasn’t already a huge crypto-only dark market where lots of rich criminals bet huge sums.

If you’re in that telegram channel, though, I imagine the threats on your life are a lot more credible than the ones discussed in TFA.

not easy because you d need a trusted central to settle the outcomes. So far, crypto has only solved the betting part
