One of those successful cases of bitcoin hodling was a friend of a friend. They (a couple) took an important risk by investing 60k of a dismissal compensation into bitcoin and making a x100 on it before selling half. I do not know what they did with the rest. Now, these people were not rich, they took an enormous risk compared to their total wealth. They had to really believe on the project and pass though some of bitcoins usual "tests of faith".
For someone with let´s say, a net worth of 1M USD or more plus house, hodling 60k until they became 6M would have been not that much of an stress. Do you think it was easier to benefit economically from bitcoin if you were already a bit up in the ladder?
The main problem is that people do not do money management when they are investing in crypto. Even a poor person can invest for long term provided his position is small according to his budget. I have seen rich people investing everything in crypto and then panic selling when they see thier port folio down.
Money management is a skill if implement correctly, your investments will be stress free.
Absolutely right, most of the people don't know How to do do Money managment though their investment decision are right and timing is also good. we must understand that No Market always goes up unchecked and they also decline and correct price which creates opportunity for traders to take advantage of this volatility and make money. The key of success to continue making money in crypto is possible with technical skills and proper money management.
