Eventually, I did with a couple of coins I did not mined them but I bought them during my initial days of trading, I did not know that we need to cut losses at a certain point if the coin is not doing well. so I bought the coins and had a target of certain % of gain on them but that never happened and I am down 90-95% on those coins(they have literally died). I don't see any point in selling them now so they are with me still reminding me of mistakes and not to commit the same mistake again.
