I myself started with the money from the Raffle winnings guessing the results of Bitcoin and got some bonuses of around $50,
but instantly it disappeared with all this one bet on a football match, it was really the first mistake I made, and eventually the money went back to gambling.
Did you stake the $50 at once in a single game? If you did, that's because you actually believed so much in the outcome of the game and that's really a terrible mistake some most bettors make, they predict a game and because they really believe that the game will go as they have predicted, they tend to stake a huge amount so that the potential win will be huge. It happened to me many time when I was trying to do an accumulation interest betting, I won many bet and because I had more confident in the last game, I had to stake with all the money in my balance and I lost it.
