Contracts have payed off in 22 weeks or less. there are 260 weeks in a 5 yr contract. right now April contracts are reaching break even in approximately 22 weeks.In my case 21 weeks. Other months will also reach break even, not in 22 weeks but slightly higher.
Have you actually plugged this in to a spreadsheet, or are you telling us what your intuition is guessing?
Yes, February contracts broke even in July, and I don't doubt that April contracts have broken even or are breaking even now.
This does not automatically mean that all future contracts will break even. Past performance is no guarantee...
Often I hear on this thread people using the word never. Never is bad math, never is a failing grade in math. Pb mining is going to reach breakeven, but its a matter of how many weeks and how many weeks are you willing to expend your assets, to receive a very small amount later on when difficulty has increased and block halfing. Those of you who bought April contracts, take a look, your either already reached breakeven or are soon to achieve it.
For a mining contract to be profitable, you have to receive more mining income than the purchase price of the contract. While the cost/GH of contracts has fallen significantly since February, so has the weekly mining income from each GH.
This calendar year, difficulty has risen around 16% on average. If someone purchased a contract at the beginning of August, and difficulty continues to rise 16% each time, then they will never break even. This is part of the risk we take with Bitcoin mining. Hopefully we will have some more single digit difficulty increases in the near future to increase our odds for profitability.
