The point is it makes me interested to sell some of our power to bitcoin customers.
Why would you want to lose money by doing that?
The only way the customers will come is if they are making money. That means they are taking your profit.
The reason to do that is to get an income to be able to pay off the electricity bills, repairs, people etc to keep the mining rig operational. Why do you think Genesis mining is selling cloud mining contracts instead of mining it all themselves? Same principle, this way it does not matter whether the coins will rise or drop down in value, you still got the same dollars you sold the contracts for. While all the miners gather coins, the mining operation is getting real dollars and doesn't even have to worry about the crypto market.
