After manipulation down...You get manipulation up. The good news is the BTC tech (and many others) has only improved.
Mind explaining why you think this market is manipulated? It's so easy for people to consider large price movements to be manipulation, but non of them are able to explain how they know it's manipulation.
Another thing is that as long as people benefit from a specific large movements (2017 bull run is the perfect example) they don't care, but as soon as the price goes the other way, it's suddenly a problem....
People fail to understand how this market works--speculators sell that what's going down, and buy that what's going up. It's pretty simple if you think about it, but still not many seem to understand.
