I've read about this pattern but of course, patterns change. (relating to a farmer investing in bitcoin) The pattern is when you have Joe Average investing in X that is the time to sell and buy the usually very stable but undervalued Y so when X takes a dive, in theory Y goes up like a rocket, then switch to Z or X or whatever is undervalued at that point that has potential. Are we not seeing that pattern now or is it X still just hitting mainstream, X being bitcoin?
