The site admin has the resources to pump the price, and has made trades that do exactly that (which made me a tidy profit).
Could you explain this in more detail? On the surface this seems very unethical.
He has 200TH of which around 3TH he has put up on market, at any point he can dump GHS. He's also mining with 200TH...so he has the BTC to buy the price up.
