I think investors don't need complicated data to map bitcoin price data. Investors are people who hold bitcoins for a long time so they buy bitcoins for long term goals. Those who need the latest bitcoin price data are bitcoin traders, traders who use the scalping method will be very updated on data and news. I'm not a trader, I only trade when I'm have good feelling and I only use data from coinmarcetcap and coingecko
I used to have a bitcoin savings program on hold. I buy bitcoin bit by bit from my monthly salary. I didn't use any data when buying because my goal is long term. But the bitcoin that I saved has been sold because I have family needs that I have to bear, and I get profit from my bitcoin savings, maybe I'm lucky because I need money when the bitcoin price is good
