Manipulate bitcoin is too hard right now you need to have more money if you want the price go increase,and if you want to dump it you will also need too much supply of btc which is hard to have now.
Just leave that to the whales, we cannot do that under our present situation, if the price will be manipulated for the success of bitcoin then there is nothing to complain about that as most likely that's what whales are doing, they manipulate to increase the price more.
True. They are owning a lot of bitcoins so they dont to lose even just for a dollar. They will use their powers for that. With cooperation of many whales it can be easily moved.
