The problem is, ultimately the larger investors dictate just how far a market will run and in which direction. At the peak of the bull run, crypto was only 800 billion, for an entire asset class that is easy fodder for big institutions to control the market. Keeping in mind that most of the market was and is made up of retail investors, thus institutions have limited competition.
The data can help in some cases, but ultimately when the powers that be decide their position, the market will follow.
