I also think that Waves will grow. Do not sell it yet.
No need to even think here, waves is a good coin to hold. This is one coin I can vividly be confident about that in the long run, it would be worth it in the long term. For those who have been following development on this coin, they will know how much the devs have been working real hard on the waves platform and with all the stuffs that will be integrated on this platform, it would make it very useful and hence valuable. Last time I checked, that is the type of coin to hold on to.
