Getting started in Bitcoin can be a bit complicated for new investors because of their tendency to take short-term profits. At the same time they want quick profit and short time from their capital. However, Bitcoin gradually allows their investment to be more organized.
In the world of investment or business we have different set of people which is Entrepreneur and non Entrepreneur and this set of people has different perspective, vision, goals and the way they go about their investment, so actually the non Entrepreneur are mostly those that has a very short vision and doesn't see the greater pictures of what their Bitcoin investment will actually be in the future but instead they are more focused on the possible way to scout profits which always makes it very hard for them to become successful on their Bitcoin investment, while on the other hand we have Entrepreneur who are known to be a goal seekers and doesn't judge based on the actual state of Bitcoin but instead they are more interesting on the bigger picture of Bitcoin and this are the set of investors that mostly do well on their Bitcoin investment and they could be known as the long term holders.
I think your reference works mostly outside crypto cause there's more to Bitcoin investment and sometimes it's not necessary to wait investment for years provided your investment has yield 2 or 3 times your capital.
