On the other hand, you don't need to spend a lot of computer power (read electricity and money for ASICs etc) to harvest XEM... You can do it for free!
On our forum there are guides how to set up your own 24/7 FREE node which will harvest for you - something you cannot do in BTC or other PoW cryptos.
Yep! Guys, set up your own node or use mine (nemnode.tk). I'm harvesting 24/7 for FREE and and that's nice.
