Can the bitcoin deposited through lightning network be withdrawn on-chain on the prediction site?
Why would this need to be a thing on Polymarket? Why should a platform implement a wallet-level feature for you, the platform is not supposed to be a wallet. It is a mistake that some platforms already do this, it creates no benefit of any kind for the users -- it is making them only more dumb and more lazy. Withdraw to LN and then close the channel to get the money back if that is what you want. Most people will not be withdrawing anything anyway, they are losing money. 99% of the users in this forum that gamble are just losing money.
A fair point on integrating LN. I’m not updated to this feature anymore but IIRC it’s simpler already to use this network now compared before that requires complicated setup.
It does not require any kind of setup now, you download a wallet and that is it -- like using any network, layer or whatever.
However, I wonder if the majority of bettor still use Bitcoin to place bet instead of stablecoin.
I doubt that, Polymarket does not come from Bitcoin circles it comes from shitcoin circles.
