I will never play gamble.. but how can I make better this situation?
i'm sorry but there is nothing you can do now to "better the situation". you have made a mistake, a big one apparently. learn from this mistake and do not repeat it and move on with your life with a precious experience.
never gamble or at least do it with a very small amount that you can afford to lose! gambling is risky. there is also a house edge which means the house always wins. it is a known fact, there is no need of any warnings. try gambling for fun not for money making.
always invest what you can afford to lose, and don't invest in altcoins randomly just because you feel they are good. try educating yourself and learn more about the market.
don't make your past mistakes again and you will make that money back in no time. and if you can't make profit from trading altcoins, then don't do it! it is not for everyone.
