In 20% increasing difficulty even machine with 90,000 MHash / s will be useless after five months .... wow. I wanted to make a machine with 320 AVALON chip, but apparently no sense.

Sorry for bad English

Mining is no longer profitable unless you manufacture your own mining asic hardware.

Why 10% anticipate difficulty? My observation is 20% difficulty. What is wrong?

Nothing is wrong, It's just my default value

You can fill in whatever difficulty adjustment you expect on the website, 10% was just an example.

The 'Estimated Date' for a new difficulty adjustment is wrong.

If the hashrate is such that a 10% difficulty increase is warranted, then the previous period was 1 / 1.1 times too short. So if you assume a 10% increase each cycle, then the length of each cycle is only 12.7272 days, not 14.

This property results in a nice expression for the lifetime yield of a mining bond / equipment:
14 * D / X
(D = daily dividend/payout, X = fractional difficulty adjustment (so X = 0.1 for 10%)

Thanks for pointing this, I already updated the code.

Enter the BTC price per MHash, and display how long it will return the investment.

Created the Mining profit calculation per difficulty adjustment projection.

If you are investing to a Mining Bond or mining with your hardware, this is to know how much is the expected return of your investment when difficulty increases.
