If you want to mine for a profit you should try the new launch promax7 which seems to mine different coins together in one machine. It is a good deal for the people who want to mine for profit. I can share the link with you, so that you can get the details of the products. This link was shared by one of my friend to me when I had asked him to suggest a miner for my use. I am gathering more details on it, if anyone has any details please do share with me.
