I think that if the bounty hunter participants know the price will go up in the future, then they will hold it for a long time
I still hold the coins from the bounty but don't have a good price yet and some altcoins are delisted from the exchange, I currently have Etherzero, I see it on CMC, I think this project has been abandoned by the developer, but after seeing the coin has 2 exchanges new, I immediately looked at the contents of my ethz wallet and waited for the price to hit $1, maybe.
