Yes for me its always been that way, need to know when to put and pull my money, and where i put my money. basicly it just about predicting and finding the right time. but sometimes that can also give me more lost or less profit than when i just hodl. also i think the most important is you need to have experience on this market. Their advice is just hold your coin its because they believe even if the coin dump they believe it will be recover sooner or later so that your not gonna lost the value in a long term.
