Boy, what a long ways we've come from March of 2015. Knowing how to analyze your investment and determine it's valuation is very important. I wonder where you think we are on Metcalf's law? Have we reached mass adoption? I don't think we are there yet. Maybe within 3-5 years when more economies are crashing . We've seen Venezuela and Greece collapse and many more on the way. At that time, BTC will be skyrocketing IMHO. Great article, thanks for reposting...
