Sounds like completely the wrong bunch of people, from the most sinister and murky world of finance to be getting involved with Bitcoin mining. Ex-Lehman is everything Bitcoin is meant to be removing itself from. Also, and no discredit to Yifu, as I don't know what he's current intentions are with current orders, I can only presume he his trying to fulfil them, but he is not the engineering talent that kind of money would be investing in, surely??
I wonder if they are going to the get the "No BS rules as well". Would be nice to see some high powered folks get the shaft from Mr. Gou.
Edit: and with no data... I am armchair quarterbacking that if any business relationships were being setup... it would be for about 1/10th the stated amount.
