Be careful on your purchase. Many of these mining rigs are sold by scammers. Go to eBay and find out they are actually selling for $8,000+ in many cases.

You will read horror stories of people trying to buy ANT miners and experiencing long shipping delays, only to finally receive their miner when the difficulty is raised rendering profits mute.

I am mining Zclassic right now on a 6GPU miner (homemade) and it's making about $500 a month currently with some lower end cards.. so for sure there is opportunity, just be careful... that's all I'm saying.
