i havent tried xmg, is there a site like minergate for monero?
is it really better than mining xmr
There is a special mining software located at
http://xmg.makejar.com/Ignore the warning messages, they just appear as the software cointains mining software (if you don't trust, check the XMG thread).
What do you mean with better than XMR? Give more profit? A "better" coin or more potential, easier to mine? I don't think you can simply compare 2 coins and say "this one is better in general", it always depends on what is important for you. XMG has some advantages as well as some disadvantages, like any other coin. I would call it a long-time investment (no matter if mining or buying), especially as it's a PoW/PoS hyrid and you can stake your mined coins.
