Everyone can benefit from bitcoin as an investment, that is if you believe it will be bigger in the future. Nobody knows this for a fact. If you buy bitcoin now for $10, it could be worth x2, x10 or even more in the future if you believe some people from the tech space like Jack Dorsey (Founder of Twitter) or Steve Wozniak (Co-founder Apple). But nobody knows for sure, so it all depends on if you believe in it. If it will be as big as a lot of people here think it will be, everyone can benefit from a decentralized paying system.
