Sounds like this was a shock to you ?
Its not a tokken swop you not have to convert your NPXS if you not want. I might misunderstand you but sound like you not have heard about the new project form Pundi X ?
This token if you will not convert it, you can still trade in exchanges, I'm not touching mine yet and there is no problem with trading
since we have a decent volume. However, I don't advise to sell at this moment as we all know price is very cheap, not profit at this time.
