You can sell them and wait for WSP to be on a exchange to buy those. Btw i'm really impressed by how this stakes compared to my old ESP, it's like a clock, a machine, works great. Not something you guys came up with but there is no need to reinvent the wheel every time and this is much much better than the almost 2 years of "development" with ESP.
I'll stop comparing the two projects from now on, just wanted to share my happiness for having swapped those things for an actually working coin (and with only 1 chain!  )
