Even more annoying, at betfury I sent some ETH but it was under the deposit limit which is like 15$, now the money is sitting in the wallet (which is my betfury eth wallet address) and will be stuck forever. I don't know how this can be since normally funds should go directly onto your casino account. Setting a limit and not moving it to the player's account is a real scam for me. At least it was only like 13$, a cheap lesson to just keep hating this terrible casino site.
You could claim it in the future if ETH price keeps going up, I believe they will also start adjusting the minimums in ETH 
I think I saw a case where someone claimed their funds after sometime when the minimums were lowered due to the increase in coin prices, though it was an exchange. That did not go without first making a lot of noise in the forum.
Unfortunately it won't cause the minimum deposit is 0.0005, just mentioned the dollar amount cause that was the price at the time, haha.
Actually what I deposited is now 15$ but the necessary amount would be like 18-19$.
So yeah, it's gone stuck forever, for whatever reason because this doesn't make sense to me at all. If a coin wallet is connected to a player's account, why would lower amounts be stuck. What I also wonder is, if I let's say deposit 3$ more, will the whole 0.0005 ETH which then would be in the wallet be transferred? I guess not.
