Cross Market sentiment: BTCUSD and Dow's Sentiment Entanglement

Cross Market sentiment Research Case Open:

The past 2 months' data showing that the fear of market comes from Dow, then it had a 8-12 hours delay to BTCUSD. I think the sentiment works in a way like this: When the market makers feel bad from the Dow, they bring the same sentiment to BTCUSD and regard BTC as a shit coin. When the market makers feel good from the Dow, they regard BTC as a worth a bet asset.

People always look at the world as what they think it is.

I am a very cautious person. I can't figure out why BTCUSD synchronizes itself with Dow in the past month for every major movement: exactly the same reactION except a 8-12 hours delay. If BTC pump back after this Dow bounce in the next 4-8 hours, I will definitely take it to an extremely important data analysis process and try to figure out the exact connection between Dow and BTCUSD using all kinds of mathematics and big data, AI processes. Cause this phenomenon may eventually response to the questons:

A. Who really control the crypto market or who plays the vital role in here.

B. How sentiment spreads in different market/asset.

C. What exactly BTCUSD is?(Digital Gold or a Tech Sector)

D. How can I quantify this kind of phenomenon?
