I read the article and it kind of went against everything that I do when I buy a coin, stock or similar.
But it was pretty decent advice.
My son's want to buy the next coin or stock that skyrockets. I always tell them the same thing. Slow and steady wins the race. If you get a stable 8% over decades you'll become far wealthier than if you get 100x for a single hit then spend the next decade trying to get the next 100x hit.
However, you are absolutely correct. If you are going to take the shot on a new hype coin. Get in before everyone else and when they do the pump cash out and run like mad after you get your fixed return. Or do what my wife does. Start by getting her initial capital back early in the run, take profile middle of the run, and hold on in case it goes way further than she ever expected :)
It's just discipline else one will get burnt badly.
Get in early. Make some profit and take out capital and bit of profit. Then let the rest run
