I think BTC mining is almost dead. There is a very small chance of making profit from BTC mining. You may make a good amount of profit, if your power is free.
True that it is very hard to make profit from bitcoin mining nowadays, but that doesn't mean bitcoin mining is almost dead.
There will always be people having the most efficient hardware and cheapest costs, and they will be there mining bitcoin with profit.
Those with less efficient hardware or more expensive electricity will eventually switch down their machines, and that will help the other miners.
