Any use for coins/tokens of defunct projects like Synereo/Hyperspace (AMP) and others?
If the projects are defunct projects just ignore. We should not feel desperate about the projects. But I think it is okay if we save the coin in our wallet. It will not disturb anything. It can be find in the cryptocurrency all the time. We can deny it.
They will feel hopeless if they have invested in such projects. I myself encountered this situation, invested a lot of money in CMT project but in the end, the price kept going down and never showed signs of recovery.
