it's not impossible in the crypto world, you can double your capital in a few days but you also have to know that the risk in crypto is very risky
It is better even not to think about these possibilities not to be disappointed after. Trading will not bring a double profit in several days. You can lose in a couple of days - this happens more often. Be ready to work hard.
Everything is possible to happen just to be ready for whatever we enter. Since you want to double your capital in two months you can just do the day trade, and you should also be aware of the coins you buy and also know which exchange to use should you be able to go to Kucoin or Okex or Houbi that's fine with those exchanges.
