I read that they are investigating criminal price manipulations over Bitcoin. Manipulation of prices is really possible ? This happened before ?
I think there is no price manipulation, it depends on the trusted bitcoin market if there are many customers who buy our coins, then the price is expensive.
That's my opinion.
Prices of cryptocurrencies are depending upon the amount of investments take place in a market which increases the demand rate and this increase is necessary for sellers so that they may be able to get advantage of the high market and get huge profit. In the current market further investments should take place if you are Bitcoin holder at this stage then you should add more to your holding coins.
