I think most of the dice players experienced this once in their gambling activities. So I thought if it's possible for dice sites to implement a confirmation message when a bet is above the specified amount like 0.0005 or 0.001 btc. This way errors like this will be prevented, it would be more disappointing if someone bets 0.01 btc or above mistakenly.
Though that one will be helpful but it's the player's responsibilities to double check the amount of their bets. There's a lot of players, aside from VIPs, who can bet bigger than the amount that OP's lost. Most of us who plays this kind of gambling surely experienced mistakes like this, some might accidentally win using the same mistakes but most are regretting since is not irreversible.
