I read that they are investigating criminal price manipulations over Bitcoin. Manipulation of prices is really possible ? This happened before ?
In my own opinion, the will not find anything about price manipulations because bitcoins value is based on supply and demand so the price will always increase if people will keep on investing.
Wow really? You don't see any signs of manipulation here? If it were just a simple case of demand and supply then we probably wouldn't be in this bear market for more than half of 2018 since people would buy in bulks. Someone who carries enough coin can and probably will take advantage of it.
