To earn profit 100% in 2 month can be possible but depend on the your strategies and lucky. Alot of altcoin has potential to raise 100% because the price oversold, i think just buy in this bottom and wait for 2 month so big probabilitas you will make it. The altcoin that still in the bottom with good team developer is OMG, ZRX.
It will be a another gamble for OP, he needs to grow his capital and with your suggestion it might lead him another failure if his capital wont be double in 2 months, that is why he needs to do some trade to have an everyday profit. He only needs to have a good luck and a good coin to have a good profit in trading.
Gambling can actually double your investment within days. You do not need 2 months for that but still it can even zero your investment. So there is a lot of risk involved.
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.
Double your investments from trading in this bear market ? Nah..I don't think so. Yes you can lose half of your investment from trading if you trade wrongly
.... I think you need to wait for bull market and then this is very much possible.
