from my personal experience i would suggest if you lose money in gambling then you should take a break and learn from your mistakes, better your strategies and do come back . and with bitcoin gambling we have many options like if you lose in one site then try your luck on others .
ps: once you recover back your money try not to gamble anymore because personally i felt its a watse of time for the guys like me who dont have much to gamble .
It is not even about learning from your mistakes.
Gambling does not have any strategy that can help you win and you are always just at the mercy of luck and the house edge and tables can turn against you anytime.
It is pure luck, and you cannot make mistake in anyway except you are betting huge which obviously increases your chance of losing more. Once you lose in gambling, accept your fate and move on. If you want to come back, know that the same fate still awaits you and if you are willing to continue, good for you otherwise, just stop and find something else to do.
Indeed, statistically, it is impossible to profit from gambling in the long run. The more games you play that more it would lead to the true conclusion, which is that you will lose. House edge also dictates that the house will win over the players if the house and the players play an infinite number of games.
Strategies only make it worse, it just speeds up the process of things. Since it repeats a set number of actions, it makes the betting process a lot faster, hence it makes it faster to reach infinity. At the end of infinity,the gamblers will never win over the house.
