How much do you estimate the mining rig will cost?
Will it be purchased new?



I agree with some of the other posts here. You are competing with other miners.

There is a very similar share CIUCIU.MINING
It is a fund for a "BitForce Mini Rig ‘SC’  by Butterly Labs" and they pay out 1% per week. Once the unit arrives, the interest paid out in advance will be deducted from the weekly profits.
