I think this is a little dramatic don't you? The stock market will far outlast MXFD or any other little penny stocks movements. These stocks are just one aspect of a much larger market. Penny stocks going up or down have little to do with overall market integrity.
I really dont think MXFD is even a pump and dump. I think you have to promo a stock for it to be a pump and dump and I have never heard about any promo at all for MXFD. I just think it has a thin (tightly held) float that allowed it to be pushed up at a ridiculous rate.
