The easiest way to stumble in a bull run is to be too greedy — always wanting to bite off all the gains from the market.

You see, this coin is rising sharply today, and I've heard people say its prospects are good, so I rushed in; after a few days, another sector has good news, and I'm eager to sell what I have to make some small profit and switch tracks. If someone shouts short midway, and the market slightly adjusts, I immediately panic and cut my losses and run.

Every day is spent chasing hot trends, seemingly making "money" every day, but it's exhausting. When you look back, the return on investment might not even be better than just holding onto the first coin.
