Funny, I thought the whole point was to hold on to the bag as long as you can. Think back to the first time you heard about btc or eth, and how much return a modest investment would have made. It's the people that sold early that lost out.
Most of the deadcoins were very low cap, and low cap investments are inherently risky. Most of the rugpulls were schemes around small coins or individuals not actually holding the private keys to the wallet.
