Oh and to answer OP more specifically:
Most big players in bitcoin trading do not care about the bitcoin technology, which saddens me being a bitcoin enthusiast myself.
They will just keep pumping and dumping, leeching more and more money out of the market. That is also one of the many reasons we keep seeing lower prices.
How will this end? No one knows...
Trading has nothing to do with the technologie anyways. One is a financial decision, the other is a technical innovation.
Please show me how your argument is relevant.
Well OP asked how the big players in trading are not concerned with hurting bitcoin by pumping and dumping. That's why I addressed these big players, for the most part, do not care about bitcoin at all. And I believe the pump and dumps indeed hurt bitcoins image and the likelihood of this technology going mainstream.
