There are some old coins that are still sitting in my wallet; Litecoin, DASH, and monero.
Though this currencies are old yet they are worth holding mate as these 3 has a bright future ahead.
I have already traded most of my old coins into the new coins that is still booming right now just like tezos, chainlink and some other coins with real product.
Sometimes we must to decide just to make sure we will not lose much when the currency fells down thats why we need to sell and regret when the price grows more than expected.
There are so many old coins that were dead right now and i have taken the decision to decrease the risk by converting a lot of my old coins. I think others will have almost the same choices.
actually i am still holding some coins that already dead now for a chance that one day when the adoption happens these coins will woke up and start making good progress.
