In my opinion, WAVES is a coin which has the potential to grow. When you look at the price of WAVES on the coinmarketcap at this time, we can see that its price is showing signs of increasing. So I think the price of WAVES will increase to $ 5 in 2019.
Most coins have increase, especially in the top 100.
Waves will definitely rise, I have no doubt on that but not as high as other successful altcoins did already.
The low was $1 happened last year, and now we have already doubled price, urrent price is $2.24 , $5 is not hard to reach your prediction
