Well, I would say that each coin in top 20 cmc is going to make 3x within next year.
We dropped too deep,so I bet there is such potential to get back to higher levels
Next year? I think it's too long. You can find altcoins that can rise up to 10,000% overnight at Yobit, although this sounds ridiculous but that's the fact. Even though this really happened but I not recommend to try it, because if you are timid and don't have enough luck, you will only get a loss.
