Idea on total marketcap

I use coinmarketcap to indicate next movements for a long time - and this works perfectly most of times.

Lets look at total cap as a pattern to analyze. It's clear that it will either bounce from a certain level or form a large cup.
In both cases I call 100-150B of cap as a bottom.

Note, a chart on this idea consists of few coins as there are limitations for timeframe and input.
