That's what I am talking about

so they are playing with customers to catch them like a fly. And 50/50 will you withdraw or not

I wouldn't say that. Gox doesn't set the price, the prices at which people buy and sell does. The current price is just a piece of information that represents the sum of information available to the market as a whole. Thelow valuation has little to do with Gox trying to retain customers, and everything to do with the information available to traders, combined with collective sentiment regarding the exchange and bitcoin itself.
