Example with Genesis Vision.
I bought on ICO sale for 1$ per token, it got listed on exchange 15.11.17, and I expected it to hit $10 by 2018 first quarter.
But the price is now right under $30. That is a growth of nearly 2900% in under 2 months.
Yes, that is the stuff everyone aims for. But it´s hard. When you take a look at most threads here for every currency there is someone who is sure that thing will rocket to the moon in no time.
It´s gambling. Diversification is the only sure bet, I guess.
