Before I knew about bitcoin and the world of cryptocurrency, I had invested in some real estate projects, but I lost money just because I did not know much about the project. After this, I invested in the bitcoin projects, I spent a lot of time on it, learn about plans, learn more knowledge that I did not know. I find investing time in bitcoin the most valuable thing I've ever spent. If you spend money to buy knowledge or add extra strength and time to acquire knowledge.
