curiosity in me to ask and know if truly that some group of people can actually determine the price of bitcoin by altering the demand and supply of the coin?
Yes, there definitely are some groups of people or even individuals who do this with out even being part of this sort of 'organization'. If you have billions of dollars, you can manipulate markets for sure. Billionaires and the wealthy in general love doing this. They simply own the financial power to put a stop on a rising or falling market temporarily.
If you said that a group of people can come together or am individual who has billions of dollars can influence the market rise, I will agree with you because they are looking for a profit, because after they might pumping the market to grown other people will be investing for in order to make profit, and once they invest the more the market will be going higher, so my question is that, which people that makes the price of Bitcoin to fall, so what's their own target or profit if Bitcoin falls? If assume we have people that influence the price of Bitcoin, they will be making the price to go up so that will profit from bitcoin.
