mine was Xtrabyte it becomes a deadcoin, but adopted by a new developer and it becomes profitable.
I do not think I have to though, I feel like once they become dead there's no way of coming back again even though there are some developers who adopted or supports it. Majority of people would be leaving the coin as well, and I either would look forward to another coin with much greater potential than the thing that is already dead. I like to try but I just do not feel the same way I feel when it is alive.
