Isn't sentiment analysis simply a market behavior synonymous with how traders make purchases by confirming them through news or rather to individual sentiment predictions? It depends on how the trader sees the movement of Bitcoin from day to day. While Fundamental means focusing on economic data that we often find today through quantitative data.
Bitcoin will never be separated from technical, fundamental and sentimental analysis. Because the current price adrift behavior is due to supply and demand. Therefore, the actual price is of course the price you see today.
It has both separated long long time ago, but also not separated at all. I am saying it separated long time ago because if Elon Musk could tweet and increase the price of bitcoin, then it means economic data has no meaning, if we could have Biden go out and say he loves bitcoin and the price goes up then there is no economic data to talk about.
This is the part where it has separated long time ago, there is also a part where it is highly connected as well. That part is the fact that while these things are not happening, when there is nothing that separates it, days like today for example where there is no big news, it is all connected to economic data. So, it is both connected, but separated at the same time.
