Why spend a fortune on mining...
...when you can use browser code to get other people's machines to do it for you. And given the crackdown on crypto currencies in Russia, China and I think Australia as well... if it gets harder to trade in these currencies, then the demand for the graphics cards for mining, might well go down.
On the other hand, I might actually be able to buy myself a decent graphics card for the first time in years... without taking a second mortgage!
