For the amount of money you just mentioned, greed will be the guy behind this. Even with 2,500, if you were betting 5% at a time, I know it can take long for you to earn up huge amount but, so will it take long if you were to lose. You just wanted to play with your whole money and get it doubled, forgetting the fact that there's also a probability for you to lose. At least you've learnt from it, hopefully, the next time, you won't borrow money from people to gamble(very wrong decision).
It's true, that wrong impressions that in gambling you can easily grow your money!
But most common mistake, they forget to acknowledge the very high risk of losing. You can multiply if either you are lucky or you really
have the good knowledge with the game you'll going to play!
without that, the chance is too slim and for most cases, it ended up losing everything instead of
enjoying the perks of winning.
