Hi

I am data scientist and CTO of one non-crypto fintech startup where we are doing analytics for US stocks and funds.
We are trying to simplify usage of metrics with charts and so, but we never use predictions for financial markets.

Of course you can use linear regression and other algorithms for prediction something, but financial market is not that area, because not everything is connected with price and volume or other metrics.
There are many aspects like war or government restrictions of fintech and these aspects can't be predicted by machine learning.

Anyway good luck with project
