when im trying to multiply my btc but accidentally lost it in one bet

Oh no whenever we loose accidently by playing the bet by mistake that is the most frustating thing that could i feel,and you lost a big amount as well,0.25 and that kind of loss could make many ones cry.So while placing bets we must be very careful because our money is at stake.
That is very painful situation when anybody lost huge amount accidentally, I also can feel this pain it happened with me when I put my all amount just in a bet by playing dice game, this made so sad and had so bad feeling about that site where was no popup notification before.
Accidently means how? in which game you lost? It will ask us before placing any bet we can continue or not. Still, you placed your bet means I think it's your fault. But seriously this is a very big loss for you. 0.25 BTC is a high amount. You should be very careful while playing big amount bet. I never did this type of mistake in gambling.
