Actually, we are not spending time. It is always good to learn how to invest. Nobody becomes rich easily. The cryptocurrencies are new solutions to become rich therefore people spend their time trying to understand them. I think it is a good thing to do. We must invest in order to gain some extra money. We also can create something interesting and get a patent but this is hard to do. When you invest, you must know where you are investing. The bitcoin education is necessary and useful. People spend time on it because they want to earn something. I hardly encourage you to improve your financial education. Bitcoins can make millionaires in the coming years. You can be one of them.
