The answer is very easy to how could you learn it. Cryptocurrency is the easy way to become rich if you get yourself employed in it.
What is the reason of your post? Are you trying to make us believe that it's easy to become rich if you hold cryptocurrencies? There's many people who bought years ago and have made 200% profit but aren't rich.
If you invested in 50 thousand usd in Bitcoin years ago and now have 100 or 150 thousand USD does it make you rich? It's a lot of money but I wouldn't even call someone with 500 thousand dollars rich.
