which coin is good for short time investment

[luffare]

Waves will give you possibilities to earn even 3x more in one or two months in my opinion cause they made some good moves on market recently.

The topic starter questioned about  a coin for a short time investment but you reccomend him the Waves coin which will in your opinion earn 3 times more in one ot 2 months. Do you really think 1-2 months investment is a short time one?
IMHO, it's a medium term investment, isn't it?
