in my opinion no one can control the crypto market. yes I also don't know for sure, is it true that the crypto market can also be controlled. but maybe people who hold a lot of bitcoins can make a price, just by selling and buying in large quantities.
need super rich people ( if it one person not company ) , to do market control , so yeah if 5-10 rich people unite to do that , it can be happens
surely that is because if a lot of rich people want to invest or buy lots of coins in the market then that will be a big impact for the market to rise. because the user had a big impact on the market
