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.
How is that theory going for the bagholders of the graveyard of dead coins and rugpulls?
You're not wrong, but has there ever been a time when buying & holding the 3 largest market cap coins wasn't a winning strategy?
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.
The purest survivor bias in a while, and even some of the few survivors are in freefall, e.g. Litecoin.
