Yes, it is possible to double capital when trading crypto but it is not advisable to trade with money you cant afford to lose. Crypto trading is high risk and unpredictable, you shouldnt be trading since you have debt to pay within 2 months. It is going to bring you more stress and you will end up making wrong decision.
Maybe, but be ready if what happens next, because sometimes in trading you will not now if you earn profit or if you lose. If you use debt for trading you cant concentrate well. But its better to trade if you have a lot of strategy and some extra money only, so that you dont need to worry if whatever the outcome.
Trading is really different from gambling, don't ever have a thought that the money you use will just disappear. There are a lot of many sources about how to trading in crypto which can be use as a first capital to start. So as you can have a think that you are really deserve to get profit from it. Unless you use money for trading then it will be good you have a such thoughts in order to eschew an addictive to play gambling. I read the OP's statement and I can imagine how he feels, he is confess that he is a professional trader but he is not sure that trading could give him the desired profit.
