Seriously guys, if you really wanna earn some bitcoin, I highly recommend thebitnet miner, it won't gonna make you rich and make you earn 0.1 btc a day like many other scam miners are claiming online, but it will make you earn at least 3 dollars per day on free basic membership using the smart-CBR service (which is also free). I've used many miners and I personally think this is the best legit and fastest miner, I'm a premium member and I earn up to 15 dollar a day with this and got paid many times!
I was doubting about it in the beginning and I only upgraded when I got my first payout but now I'm pretty happy with it
You guys can sill use it for free, it works! You just need to be patient to reach your first minimum withdrawal!
