I guess everyone here noticed some decline (hopefully temporary) of almost all coins people used to gamble with.

Is it affecting your gambling?
I don't think it will affect any of the gambling practices because our rewards are only calculated in terms of bitcoin so the rewards will be the same only the value is changed,so I think now people can deposit more amount of bitcoins but only the winners maybe worrying that the rewards are less than before.But don't forget that the price of bitcoin is still at $9000 which was around $3500 before 4 or 5 months.
It will effect, it has to. Most addicted gamblers will get a chance to increase there gambling capital, yeah Bitcoin or any other crypto currency is the one used to calculate the rewards, but still now we need to first convert our fiats to Bitcoins etc., so when the rates are low, we get more amount of coins and it helps in increased betting or gambling stakes.
