For me, I think financial stability works behind our success in life. So same goes for Bitcoin investors as well. The rich person could invest for a long time. He doesn't have problems even he doesn't sell his holding even during very bear markets. A financially stable person even could hold 10 years. But like us who are small investors, we aren't stabled financially. As a result, we don't when we have to sell our holding for need. That's how we become losers even we intend to hold for a long time. I am a real example of that recently.
Do you think financial stability is mandatory to be a gainer in Bitcoin investments?
Depends on the meaning of investment. If you mean investment to just simply buy some crypto then anyone can do that, even the poorest person can do that, the amount doesn't really matter, sure the tech part could be hard if you are like some homeless person but even they could use some of it to buy food and some of it on some bitcoin ATM to get some more. Everyone can make a crypto investment by simply buying, even 10 bucks worth of BNB means you are invested.
However if you want real investment, investment that could really make you become rich one day, you should do it by starting a business related to crypto or at least have a business investment even if it is someone elses. That is the one that makes you a lot of money.
