Just like the price, the marketcap is not really important. It actually means nothing and It's much lower then 100B If we take in consideration the lost and untouched coins.
What you really need to look into to know If we're progressing or not is the number of ATMs, services, local shops etc. that accepts bitcoin and how are they growing over the months.
This post is a very logical one and have really treated the cacophony about marketcap. Really, it means nothing in the sense that, it does not have any effect on bitcoin adoption usage etc or neither would it affect bitcoin too. Marketcap to me is an after effect and nothing more.
It simply shows what people's decision are on the coin. More like an index/indices, table , graph etc. What matters are what countries are making positive moves about it, stores adopting etc which only shows in the "graph" as marketcap .
