Hey all,

I have been mining for some time now with two antminer s7s and one antminer s5,  hashrate totalling at a little over 10Th/s. With that hashrate I am able to generate approximately $100(0.025btc) per week given the price of 1 btc remains over $4000.

Not forgetting to mention that I am not paying any money for electricity due to the location of these miners.

I am interested in upscaling my mining operation with a start up capital of $5000.

What equipment would you recommend?

I have been thinking of continuing with antminer s7's due to the availability of them and their low cost.  I belive that about three s7's will give you the hashrate of one s9 however the power consumption is triple,  however,  power consumption isn't a worry for now.  Secondly one antminer s9 is currently being sold in the range of 2500$ -  3500$, where as one s7 would be about $700.

Let me know your thoughts on this.

Thanks
