Undoubtedly, most of us have dead coins because we joined scam airdrops and bounties for failed or scam projects, these dead coins that we received are of no use, but if we hold them in the long term, we may be lucky to get some profit from one of these coins, If you do not want to receive these dead coins in your wallet, you must, before you join any project, make sure of it, its information, and the team behind it.
we could not avoid shit project and shit token in this market either come from airdrop or bounty campaign. not all developers team have good quality developting their project, some of them even only just kidding while they create it. research will be main key to find best project in market.
I try not to keep those kind of coins in my wallet as much as possible. I sometimes see that there are some coins which I didn't even hear about them. They sometimes are locked or open to use. However, I really doubt about these kind of coins as they can be the coins of a scam project. And I think about the possibility that scammers or hackers can hack my wallet somehow while I am using those coins in an exchange.
that possibility happen , and recently i heard this case. suddenly there is new token come to our wallet and try to traded in exchanges but unfortunately our rest assets hacked. we must carefulll with strange token that come to our wallet, better move them to temp wallet that contain garbage token.
