Waves is a stable investment and a long term one tbh. If you are intended towards waiting and can hold till you double, then no doubt Waves is such an invest-worthy asset for everyone to try their hands on. I am currently having 100 Waves and holding them for a very long them until they go ten folds.
The way bitcoins are increasing in their value, it would be absurd to think that they will pump before the New Year. I will recommend holding bitcoins at least till November to enjoy the highest profit ever made by any coin in the history of crypto market.
After November fork, there will be big pump on bitcoin. If Bitcoin win the fork against the Bitcoin2x, I mean bitcoin2x fail like BCH, the price of bitcoin will be unstopable. It will rise highly, I think keeping btc is more profitable than waves.
