Is about the community, there are more users in the bitcoin markets than users in the stock markets... Is easy for anyone to buy bitcoin, even a kid can open an account on an exchange and buy coins with the Paypal account he uses for his games.

There are some whales and beers in the market, but take the example of Tesla... he buys 1.5B and that is less than 2% of the full market, so, bitcoin is volatile because there is a lot of people involved.
