I used to do Air drop and bounty. Get all coins in time when the market is down. The value of all these coins lost 90% even now looking at it I do not believe it is no longer valid.
I cannot sell them because no one buys them, and its value can only be enough to transfer to exchange.
So do you have a way to hide it or delete all the coins from your wallet?
Don't you worry, your not the only person here who have that scenario. I know its kind of annoying to see those shit coin that are nothing to give any help to us, but it will be there forever as long as the blockchain exist. Who knows one day miracle comes with those coins to be alive again
, if you really like to forget them, you can change the address then leave and forget that address anymore.
