Since I started bitcoin in 2015 there are already bitcoin gambling sites and today they are still existing. I'm just thinking if gambling is one of the factors in increasing the bitcoin's value.
Every successful Bitcoin business increases Bitcoin value, but the real question is how much? Bitcoin gambling boosts demand for Bitcoin, because people need to buy Bitcoin on exchanges to deposit it to their casino accounts, so how much Bitcoins are bought for gambling? I think it's possible to get some idea about this sum by looking at casino profits and then multiplying it by 1.95 (something close to effective House Edge). It would require a lot of work to find the sum of profit for all casinos, but lets say it's around 100 BTC per month, which transfers to 195 BTC buy support per month. Some part of this sum is later sold by players who won or casino operators and their investors.
