mac_angel, that doesn't sound like what this article is saying at all. My current Asus Z170's exhibit the behavior in the article. Cards come up, but they have yellow exclamation marks. This particular 4G option is new and most definitely *NOT* available on all motherboards. I've put together dozens of computers over the years and I don't remember ever seeing any "4G" options until recently. What advantage does this option have other than allowing more than 4 GPUs to have enough resources to work that would have made it's inclusion necessary?
Photonboy, look at how many financial institutions are getting involved in cryptocurrency. I've recently read articles about JP Morgan using ZCash blockchain technology and Fidelity Investments getting into mining/trading. There are financial traders that love getting involved with buying high/selling low that inject money to get their stake going. I could go on an on, but a lot of people are injecting real money (depending on how real you feel government backed fiat money is) into these systems.
