Crypto currency breadth chart

Out of interest I've calculated some breadth charts of bitcoin price versus breadth of a selection of cryptocurrencies listed on Wikipedia as the leading cryptos.
https://en.wikipedia.org/wiki/List_of_cryptocurrencies

I had to omit one or two owing to lack of or poor data.  I've used bitcoin as the 'index', I could not find an overall crypto index and bitcoin is obviously the leading crypto at present so seemed a reasonable choice.  Whether other cryptos correlate with each other, or especially bitcoin is an interesting question.  If there were no correlation you would expect the breadth chart to just be noise, which is clearly not the case.

The Weinstein Momentum and Cummulative New Highs - New Lows are interesting as they seem to confirm trends for bitcoin.  Not so sure about Advance / Decline and Advancing / Declining volume lines but that may be an issue of graph scaling.

I've plotted 1 year, 2 year and 5 year charts.  However, the older you get the fewer cryptos that I have data for and that data is likely to be less good.
