You got it wrong. It's not about the cost of 1 share. It's about the dividends! jommothy stated that a successful gen4 chip could bring in 1BTC per share in dividends form. I would like to know how he got to that number so I can see it's not just an attempt to raise the share price.
1btc per share in dividends for Gen3 is ridiculous, admittedly. However, If Gen3 hits 15% of the network and Gen 4 hits power/Gh estimates then it is entirely possible that 1btc/share market value is possible.
