That is not a knc employee. That guys is from Accel, the people who just invested $15million. They obviously have seen kfc's books and know exactly who much they are making. If they are willing to invest $15million, then the cash flow has got to look good.
kfc's biggest outgoing is the $450,000 electricity bill each month. Also, they have to replace miners which break down and replace them with new ones every so often. But that isn't too expensive - you just clean the dust off them and send the broken ones out to customers waiting for their bonus rigs

Kottings on the KNC board now. But I take your point about their books, but as you probably know, investments are made on a number of factors, cash flow/turnover being just one. I would think the KNC data centre alone is worth much more than $15mil so investors have millions in assets not mention IP to liquidate if it hits the fan. Interestingly KNC have been quick to spout turnover figures but remain suspiciously quiet when asked about profit. There's a saying: Turnover for vanity, profit for sanity. Their annual report would be an interesting read.
