I personally don't look into any fundamentals or function of the coin. It matters none to me. If I were on an island alone and only received hourly/dailuy price feeds, my projections and forecasts would be the same.
Fundamentals have no bearing on technical analysis. It has lots of bearing on human sentiment and for that many want to know more about what they buy from an informative perspective.
For cryptos and equities, I only use Technical Analysis.
