I don't think it is impossible, it will just be slow.
Yes, that's why I said "fast game"

.. for a fast game like dice
Yeah, I read that. (just read don't think it is possible part too many times

)
I wanted to know your opinion on everything except that part - If satoshinonce accepted investments, is such a risk entirely eliminated?
Although in theory in the future there could be true decentralized trust-less gambling/investing with sidechains and investors that run some program to sign transactions/bets on the fly (like JoinMarket.) That would mean all investors have to put their BR in a (own-controlled like their own computer) "hot wallet" though and it's not as fast as dice now. Also I am not sure how the random process would work (either dependent on miner or third-party like most ETH smart contract gambling atm.) So I am not sure how practical it will all be, but sounds like a technical interesting project when the time is there

I think decentralized trust-less gambling/investing is very possible.
let's say this problem is solved and investors can't be cheated by casino owners. it will not solve the hit n run option for a casino owner imo and this would mean that investors coins are always at risk
at the end the magic word will be trust (the casino owner)
If everyone is really going to trust the owners we could do away with the provably fair too.

provably fair was invented for the player and imo the best invention in gambling business so why to do it away? please correct me if I am wrong
Er.. was saying, provably fair wouldn't be invented if we kept thinking - it will not solve all the problems and all we need to do is trust the casino owner.
