I also have number of coins in my wallet that can be considered as dead. Through the years that have passed, I have come to accept it and learned not to let my mind linger on this lost profits because I cannot do something about it anymore. Now, I am focused on scrutinizing the projects that I get involve into and conduct forecasts with regards to the potential of the coins.
This step is very correct, instead of wasting time on coins that have died, indeed when talking about losses everyone gets these losses, but if we keep talking about these dead coins, we will be even more lazy to invest, it's better if the coins that have died are forgotten of course, there is no further movement of the coin even though it is done in any way to be pumped back, just focus on new projects that are able to generate and can cover the capital of the dead coin.
I am glad to know that you agree with me. It is pointless to stay down because of dead coins, it is okay to grieve over it but then we must move on. Before, I also had wishful thinking that maybe someday this coins will just pump but I also realize that thy will be done. No matter what happens, I will focus at the present and strive to be wiser in making decisions.
