Showing where the coins mined benefits us nothing. If he was indeed mining this whole time, it will be easy for him to just send out the coins but in fact he hasnt done such things yet .
Another speculation could be that he was indeed mining but due to his greedy nature, he sold more than what he could pay with all his hardware (he sold an ASIC boards before ) .

However some people just cant let go this sad fact and keep on waiting hopelessly to all his promises. Conclusion will be that he is not legit at all and this is a ponzi
