Sorry for your lost but as I said previously, it is your own responsible. It sounds that you are blaming coinroyale because you won so small amount only from the competition while you have lost bigger amount than the prize you got. There is no lies here as far as I understand, the 2BTC prize is the total prize when there are 20 eligible winners. It seems that you were so sure to win something great on the competition but you are not ready for the worst case.
