Having a 200% yield in any other financial assets it going to be spectacular, only for bitcoin 3x is considered "meh".
The point is you are thinking on a too short time horizon. We are talking about intergenerational wealth here.
Well, doing a x3 per cycle, and decreasing surely each cycle, if you invest $50 is not going to change your life radically, if that's what we're talking about here.
Then you have to think about something else: the person who invests $1k in Bitcoin, who normally does it because he cannot invest $10k or $100k, how long can he hold on without selling when it goes up? It is normal that if it makes a x5 or x10 at most 99% of people sell. You have to have a lot of patience and know about personal finance as well as good management to see it go down from the peak without having sold and endure 4 years of bear market.
Becoming rich is not that difficult, in the big scheme of things. One good idea, a bit of luck, or an incredible skill (think of Leo Messi) can lead you to become very rich.
Without becoming very rich, everyone can become rich without having a special talent, simply by spending less than their earn and investing their savings. Month by month, year by year, investing and reinvesting.
This is reflected in the book
The Millionaire Next Door, which was criticized at the time as having a small sample size of less than 1,000 people. Years later the book
Everyday Millionaires: How Ordinary People Built Extraordinary Wealth--And How You Can Too with a sample of 10,000 people had very similar results.
Regarding the Twitter thread, it's not the first time I've seen a thread like that, and just now after how disappointing this cycle has been in terms of returns, I'm not getting my hopes up too high. Besides for me Bitcoin is just a part of my wealth building plan, which I have been following for a long time, copying what those two books reflect and which is a safe but monotonous way to get rich.
Since I became interested in personal finance many things have changed in my life. At the beginning everything seemed very difficult and I started with what everyone does: saving, then I controlled expenses, then I started investing, and to top it all off I came up with ways to get paid more for my main job and to obtain other sources of income. At the end there comes a time when everything becomes easier because you control income, reduce expenses and make more money month after month, year after year. What happens to a person who does that? They become rich. And this taking into account that I donate regularly, I take it as an expense like paying the electricity, yes I donate, I give money, every month, and every time I get richer.
