It is true that through bitcoin, you can learn about it, understand it, but in my opinion, bitcoin is really an investment, you can buy, exchange, can use bitcoin to participate. Enter the ICO of the project you think is potential, and can store the same as gold reserves. It can help you make more money, and it can also cost you money, but some people will invest based on experience as well as knowledge, not a kind of gambling. Because profit comes with risk. With the above, is not it really an investment?
