The manipulation you speak of is no secret and I struggle to see how it is any different to the current market. I think the harsh reality of it is that in any system where the rich, educated and experienced can take advantage of the poor, less educated and less experienced for their own personal gain - then that will happen. Hopefully in time the market will grow to such a size where manipulation is much more difficult. One disadvantage crypto has over forex, stocks etc is that due to its decentralized nature it is near impossible to regulate manipulation and stop collusion.
