What returns on my investment do you offer and how safe are these returns?


Bitcoin Mining is hugely profitable, and we offer our investors an monthly return on their investment of 57.28%; this is the equivalent of a return of 1.5% per day, compounded over a month..

Therefore, if you invest with us for 1 day only, the return on your investment will be 1.5%. If you invest with us for a month, the return on your investment will be 57.28% (1.5% compounded over a month).

Our return on investment is guaranteed, irrespective of macroeconomic factors..


What is the minimum amount I can invest and can I withdraw my capital and profits at any time?


We do not have a minimum investment, and we welcome small investors; whether you are a small or a large investor, we do recommend making regular investments over time, as these hedge against fluctuations in the price of Bitcoin.

You may withdraw your capital and/or profits at any time online, and you can do this from within your account. There are no withdrawal or other fees.

What is it that you actually do with my investment?


We use your investment for the sole purpose of improving the efficiency, efficacy, and size of our Bitcoin mining pool, in other words to mine more Bitcoin per day.

This includes improving and fine tuning our hash rate through motherboards with multicore Intel processors, capable of supporting 8 video cards (GPUs), DDR4 RAM, SSD hard drives, and Plus Gold power supplies.. Whenever possible, we add to our mining rig with additional Bitmain units.

We also pay the fees of world class blockchain developers who help us improve the quality of our mining software; to date, over 1,200,000 lines of code have been added to Jamie Darnley's original code, allowing Darnley Mining to simultaneously hash all known mining algorithms at breakneck speed. No other miner can do that.
