Dead coins don’t just come back to life.
This is true, if it suddenly comes back alive. It's a typical pump and dump and it's not worth it to spend time.
There could be more from that and it only takes an experience for someone to realize that it's not worth it to get onto that because it means nothing to be honest. I've got a lot of those bounty tokens that are worthless now and I just kept them, luckily, I've sold some before they even became worthless.
