You guys realize, that the issuer automatically owns all unsold shares, right? No need to buy shares from yourself if you own them anyway.
Not exactly this way. When IPO will not be sold Cryptx and they dont buy not sold shares they will introduce less total hashrate and divide it to number of sold shares will give us 15gh per share but they will not collect dividents. But they will be able to introduce another ipo with not saled shares. When they buy uunsold shares they will simply collect dividents as normal shareholder and can not launch new ipo.
