I put all of them in the Recycle Bin and delete them permanently to free  up some hard disk space.

There is no way that someone will not experience this type of things in the course of crypto trading but before you can do anything with your fail coin you need to see if it could be revived or if it has future but in most cases it is better to wait.

Since its a dead coin I'll just stock it into my account in exchanging site who knows it will revive again plus it's additional design to my account seeing numbers of coin.
