Dear,

I was trading Coins since some time ago and I want now to get into mining, so I was reading some tutorial from here and there, and I'm feeling lost, so please I want to get an orientation from you guys,

My questions are :

1) Which better coin to mine now, I read that ETH is the best right now, is it?
2) I am planing to make a rig of 6 GPU, so which graphical card should I get,taking in consideration that the electricity is very cheap for me
3) If there are any tutorial to help, I will be grateful

Thanks
