Those are good reasons you stated, but it's not all I guess. Another factor that really really make people want to invest in bitcoin is because its value and price. We have heard many people getting rich because of bitcoin, and don't tell me that I'm wrong but I'm pretty sure a lot of new investors came to this cryptocurrency world because they want to experience the same thing. Because they've heard that many people get rich from bitcoin, and that bitcoin is such a good investment. People want that profit as well, and bitcoin sure is such a great investment choice, so why not?
