I know a plumber who was asking me if he should invest in BTC the other day. I didn't tell him yes or no, but I did start talking about risk, zero sum game, and the differences in investing in for profit companies and commodities. We are at the point where someone who doesn't even own a computer (other than his phone) is wanting to invest in BTC.
