Bitcoin Miner hardware kaufen

It depends on where the difficulty actually ends up and what the price of Bitcon will do. I have made a simple calculator to figure this out.Given a specified mining rig and electrical utility rate, I can show you at what difficulty your rig will not be profitable, compared to the current exchange rate of BTC. This should be applicable to solo or pooled mining.

Here is an example:
BFL 5Gh/s ASIC Miner in BLUE (more efficient)
Power consumption: 35 watts
Price of electricity: $0.10 USD/KWHr
Block Rewards: approx 25.5 BTC (25 for block.5 for tx fees)

Avalon 63Gh/s ASIC Miner in RED
Power consumption: 600 watts
Price of electricity: $0.10 USD/KWHr
Block Rewards: approx 25.5 BTC (same as above)
