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. 
For me yes, bitcoin mining is always profitable base on the actual experience of mining, me and my friend are now using antminer D3, we are happy in the result of generated bitcoin everyday we are now planning to add equipment for much better result. All our mined bitcoin was kept it in our offline bitcoin wallet to make it safe and we sell it when it can purchase new antminer again.We are hoping that next year would be more profitable for miners like us, OP, yes it's still profitable provided you have relatively cheap electricity. You'll have to take care of cooling and maybe (most likely not) power capacity upgrades in the area where you plan to mine depending on how many miners you're going to purchase.
Keep in mind that the money you'll make is not much, keep in mind that you will also have to buy new miners when they come out because the old ones become obsolete almost immediately.
