I also have a lot of coins like yours and I have been holding this coin for 5 years till now and when I looked into my wallet, it turns out that shitcoins are still not getting a good price even though Crypto is currently on a high rise or maybe have to wait 20 years for the price of the coin and hope the coin community doesn't abandon it.
Too many shitcoin has been obtained from bounties or airdrop, Until now, no shitcoin has been able to move in a better direction. 5 years are not a short time , but the reality still not able to give anything. I'm not sure if you'll be able to endure the next 20 years to earn from shitcoin, because coins that have been abandoned will never be developed again.
if it's been 5 years, maybe starting from 2017, then I think there is little hope for this coin to grow again, especially if it has been abandoned by the developer. but don't be discouraged because sometimes there are pump and dump incidents on this shitcoin, and I think this is just luck
There will be no hope at all. Never expect developers to return to a project they abandoned. Instead of going back to developing old and outdated projects, they will try to follow the market trend to create other shitcoins or more potential coins. So don't expect it to just tire our mind more.
