Wormminer has NOT raised the prices on the mining rigs for June yet. You can still get the 2017 rates so be sure to get registered and place your order for a mining rig now. The best rig to get is the Gianter. You will earn 410% return on your investment.
If you have questions, see my training videos at www.FreeBitcoinmining.info
