I'm new to all this, so go easy with me. I searched a little bit and ended up making the decision of mining using 6 GPUs (Nvidia GTX 1070). The electricity cost in my country is like 0.05$/kw (If not lower) and planning to go with Ethereum.

1. Should I switch to another crypto currency?
2. What should I understand before starting to mine
3. I'm going to follow this . How bad/good are the instructions and information's there?
4. Solo or pools mining?
5. How much hash power I'm going to generate? 180 Mh/s?
6. Is this accurate?
