I'm probably going to get rid of my Waves as well somewhere during the summer. Depending on the development. If it starts moving then great, I might keep it (or if there are great news just around the corner), but if nothing happens then I might dump and go for something more interesting.
I am very close to ditching my Waves for COSS, but I just want to wait a liiiitle bit and see how things work out. However I'm afraid that if I wait I might miss the incoming train on COSS, even though I do hold quite a lot of COSS tokens.
