I came back to London after being away for a while and noticed something is different. Now there is all kinds of bitcoin (and ethereum) commersials all over the place, trying to sell people crypto investment services. I've always been told that if investing becomes so popular that it is discussed in the pubs you should sell. This makes me kind of worried. What do you think?
I don't think bitcoin is being thrown at people's faces just yet, at least not in the United States. I'm not sure the "London Underground" qualifies as mainstream. In any case, bitcoin carries some risk just as all emerging technologies do. By diversifying, the impact of its volatility will be minimized.
