Traders and Specially Buyers, If theres no Buyers and Sellers the price of a coin on market might go down because theres no Volume on a trade specially when you are going to sell tokens but sadly no buyers like the price was $10,000 but theres no buyers so U cant still sell it.
Traders and buyers run the market and do not control the market. There are some people who controls the crypto market and which is not acceptable to investors. When I know that the price is manipulated and big investors change the market according to their wishes I will never invest in it because I know that they will never let me make money from my investment.
