One guy I know - who we dont want to ask but be sure of that - makes 100k Dollars a month with mining ETH in Sweden. (ETH Price 700 so now it would be a lot more)
So he and some friends of his own a mining farm.
How do they do that? We dont want to use Google because we are sure that what you find there is scam.
Does anybody know an answer? we also have a screenshot but i m not allowed to post a picture
If you know any person or friends from the local electronic market. Reach there and ask for the graphic cards like Nvidia 1070 or Rx 470 cards. These cards are good to make the rig with the prominent profit.
For rig you can make it with the aluminum scales and wooden sticks to make the rig as you want. You need to buy the SMPS, SSD, mining mother board and RAM according to your preference. Buy ask for the person who is making the rig set up or watch the Youtube video and do by own.
