I chose PB Mining to mine Bitcoins in the cloud, because I did not want to purchase expensive hardware and had no experience mining Bitcoins. After using the service, I have identified some key points:
No Mining Costs Deducted – There are no hidden fees with PB Mining. You will not pay for operation costs or electricity costs. You simply pay the current hash rate price in Bitcoins and receive income for the life of the contract.
Weekly Payments – PB Mining pays out your Bitcoin mining proceeds once a week on Sundays to your external Bitcoin wallet. You can either reinvest or pocket the amount.
Price Per Contract Goes Down as Difficulty Goes Up – With every increase in the Bitcoin network difficulty, PB Mining lowers the price per GH/s. Therefore you can purchase new contracts with the same yield as the old contracts.
Fast Start Time – As soon as you buy a contract and send the exact number of Bitcoins to the specified address, you are up and running within hours.
Cheapest Cloud Mining in the Industry – So far most cloud mining companies can be considered scams, because you cannot make your initial investment back.
Profitability? – The profitability of PB Mining is still questionable, because of the current exponential difficulty increases. I calculated that if the difficulty increase is 15% per month, you will recoup your initial investment within 4 months. If it is 30%, which is the current rate, you will recoup your initial investment within 6 months. Also, if the exchange rate goes up significantly, you will recoup your initial investment, assuming you bought Bitcoins with US dollars.
No Personal Information or Credit Card Required – You simply purchase the contracts with Bitcoins by depositing from an external account. I used Coinbase. No other questions are asked.
Generous Referral Program – For every person that you refer using your referral link, PB Mining will give you 10% of the hash rate for all of their future contracts.
