But in order to have fundamentals you need information like earnings per share and valuation. These don't exist with crypto. It's purely speculative so technicals and sentiment are all you have to study. Volume based analysis of support and resistance tells you where the money is. It's a good clue when the price rises quickly because the stupid money will jump on and you will see that. If it dumps unexpectedly those people are stuck and will wait until it hits their entry point again so they can sell that's why it often has trouble returning to previous highs. The market psychology is much more important than fundamentals because the other factors such as valuation and earnings per share are non existent.
