indeed everything can certainly happen, but I myself am not sure if for 2 months you can double your capital. in the good crypto trade, calm is needed. I know you are being chased by a problem, and certainly it will make you very nervous. indeed there are many people who are successful in trading and they get profits in a short time. but I think all that can not be separated from the luck factor, especially those who succeeded in 2017 ago. It's better if you don't target with such a short time, it's better to think of how you can earn money when trading, and hope that you will get good luck soon like those who invested in 2017.
Current market is very volatile so making a double profit in the short term will be very unlikely because you are not always lucky enough to do this. In fact, even if you are a professional trader can not do because any coin in the market has a great risk of investment. Of course if you are patient enough then you should try because one day you will be successful with that investment.
In my opinion, instead of having to get double profit, you should find ways to make profits everyday and must know how to control your investment.
