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?
Yeah. Not relying only with your investment for your daily needs is really a big deal. If you are poor you can't have that freedom of investing your money without taking a toll on your day to day life. However, the first thing in crypto is that you should invest what you could always afford to lose. This is probably the best advice for anyone who's into crypto now and even Cz told us that
If you cant hold, you won't be rich
