The short answer is no. The long answer is worth hearing. It's not a get rich quick scheme nor is it easy. Most cryptocurrencys will never amount to much. You must do research on what a project is about. What problem does it try to solve, what does it try to improve. And sometimes even good ideas fail. It takes a strong team, a clear vision, and maybe a little luck. For we investors, it takes lots of investigation and an effort to remove emotion from our decisions. Many people have sold their investments for losses out of fear. Fear is a damaging emotion. Think about what would you do if you invested today, and the market fell another 50%? Could you have faith in your choices, and ride it out? Or would you sell in fear of losing all your money?
If you invest poorly, you will lose money. If you invest well, you will make a lot of money! So no, I don't think you can live an average life investing in cryptocurrency, you will live poorly or you will live abundantly! Good luck!
