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.
These are classic stories and other players, they have their own, but they have common features. I recently started watching a video in which players talk about their path in which they tell their feelings and emotions in detail, it became interesting to me because I try to understand how it all works in our brain, and besides this I do not want to repeat the mistakes of others. I hope this will help me in the future in the game, so far I understand it for sure not to think about what we will definitely win, we must have more real thoughts and think through even little things, for example, what we will do if we lose. Most players do not think about such simple things at all.
