As compared to cryptocurrency market, the prices of stocks in stock market are quite stable. Unlike various altcoins, they do not suddenly increase or decrease (pump or dump) with 30-40% in a day. Is this because less people are into crypto market and the cryptocurrency prices are controlled by those who have ample amount of coins?
yes, people / communities with large funds easily control the crypto market unlike stocks that have control of the company according to product quality
Of course, they can, but the question is could they handle all of the crypto markets at the same time? We know that in out there many big exchanges with a big volume trade daily and there are small and mid-range exchanges, so they need to have bigger power to handle.
I am sure that many people are into crypto, and they still trade in all exchanges, but the mass adoption will not make the crypto price stabilize. If there is a demand, the supply will come to serve, and there is always up and down many times daily.
