To be selfish, you can just sneak in the coin you like. The market usually says that it is either too big to chase or you will be trapped first. So I can just go in by myself. The coin is too heavy to pull. I think the direction control and every hint of buying at the bottom and selling at the top are good enough. As for catching the sector rotation, it is also simple. For the coin with good fundamentals that has just come up from the bottom and is on the gain list, you can grab the first wave of callback opportunity and get in.
