If I would start BTCmining this year do you guys think that it would still be profitable? After all there is already lots of miners out there not counting the farms. 
Never believe the propaganda about mining farms. Those are fraudsters at work. They are showing you the hardware but they are not showing you the internet connection routers. You cannot mine with electricity alone. This fraudsters are making you feel inferior by making you think that they can set it up on their own. They can't. Most of them are so stupid themselves. Bitcoin mining will always be profitable. Don't believe the stupid YouTube videos about mining farms. It is a sleight of hand. After the camera stops rolling. They will close the circuit breaker.
