i belive that is a good way to see what the real price of bitcoin. i compare with btcusd, when him stay up candles we have happy. when estay down we desilusion.
the graph start in record price in 2017. when stay red them bitcoin up togheter with crypto market down or neutral. If is green btc down and crypto market up or neutral. basically you can see percentual change in terms of bitcoin value.
this formula should be one but in real world the market with fiat money is more profit if this is major that one. another way if is down of one is better operate in cripto market with btc as standard. If you in top or maximo value this is best day for call or sell, as color candle tell you, in fiat market. then if you in minimum value this is the beste moment...
I believe that gold is best standart for all coins. a simples view of bitcoin vs gold
