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 The value of all these coins lost 90% even now looking at it I do not believe it is no longer valid.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?
Wow, it's so unfortunate. Most airdroppers and bounty hunters are in same predicament. The issue is that you can't actually delete your tokens from the wallet. At best you can hide it on Imtoken wallet by removing the tokens highlighted on the wallet. You may need the ticker or contract address to be able to successfully carry out this on the tokens.
