Kindly recommend few best cloud mining websites which guys have been using.. There are few sites which offer free Ghashes. Are they worth it? Ur views
CEX.IO was the most trusted as far as I know, but they shutted down their service to the price drop in Bitcoin. but they will probably open once again soon .
anyway , I wouldn't suggest you to use Cloud Mining , it's not Profitable at all these days .
