Crypto manipulation
Could one entity or a syndicate buy with fiat, a substantial no of bitcoins, and sell in unison thereby driving down the price and then re enter the market, buy more at the lower price, by so doing, over a period, take control, to some considerable degree the bitcoin market and the price?.
Of course.
The Bitcoin market can only be manipulated by buying which can make the price go down, but on the subsequent purchase the price would tend to go up again with a net sum of zero. Unlike the equities market which can be manipulated with derivatives, short sells, etc. I placed an article in Steemit on Thursday about this exact scenario.
