Yes, but I assume it's those very rich dodgy guys that are grouping together to manipulate the price, It's open to manipulation due to no regulations, and you have rich guys on this planet who love manipulation of markets. Bitcoin is the perfect opportunity for them. They don't need to keep increasing the price, they just need to get the hype back, and cash out at a certain point. Easy manipulation for a big group of rich guys. I've seen small groups do it with pump n dump groups on smaller cryptos.
