Any good conspiracy theorist will notice that the up and down movement usually occur in a $50 fluctuation cycle, and this indicates manipulation and mini pump&dump scenario. There has to be someone behind this, and they are making tons of money because of this. A group of whales on different exchanges could manage to manipulate the price in such a narrow margin, and still make a lot of money. I hope this is not true and normal supply and demand are causing this, but it's just too obvious. ^hmmmmm^
