The Clipper Ship Strategy: to make money during a gold rush, focus on supplying a secondary demand created by a primary boom. Chances are, it'll have drastically less competition while being just as lucrative.
Cryptocurrencies have a similar situation unfolding. Everyone is trying to get rich buying the 'coins' in order to sell them to someone else later. This is extremely risky, and just as many people will get wiped out as will make money. It's one thing to buy bitcoins if you're worried about a paradigm shift (like I described in my 2013 article on Seeking Alpha).
