But through Bitcoin, we learn how to save or accumulate it and then wait for the right time to sell and make a lot of profits, rinse and repeat. I do agree that fiat will still be there no matter what, but at least with Bitcoin, we have learn a lot from financial perspectives and we are making some decent profits from it thru holding and investing on it for the long term.
What was the reason before? Why weren't you interested in investing? There's a lot of information on this topic on the Internet. Personally, I started paying attention to it when I read Kiyosaki's book a long time ago. It really got me hooked. Since then, I started learning what and how. I even tried to create my own investment portfolio when I had no money for it, but I started saving.
A lot of time has passed since then, and I still continue to move in this direction. Yes, of course, there were many trials and errors, but I don't give up.
