100ROI in next 85days assuming the difficulty doesn't raise!
Difficulty alone is irrelevant. Most important in this aspect (ROI) is ratio diff/price of BTC. If this will stay at similiar levels then ROI in 85 days. Future will tell how it will be....
It will be the same difficulty or less for the next 15 days :
-1.51% in 0 days Next difficulty
But it is likely to raise within 85days.
I read in a different thread that the reason for difficulty going down is PayCoin. A lot of Sha-256 miners are most likely mining PayCoin and hence bitcoin network has lost a huge hash power. Is that true ? Does anyone have any data regarding this ? Is PayCoin mining really profitable or it is just speculation ?
You can find this alt-coin thread in the alt-coin section. If people are mining an other coin and the difficulty doesn't increase for Bitcoin for an other few months, it will be great for miners. Then the price of BTC can rise for everyone to feel a bit wealthier
The following graph shows that difficulty and price generally goes hand in hand...

So, difficulty drop may not result in a price rise.
If the difficulty goes down, the miners will make more BTC. I am hoping the price will then rise for all miners to make a nice USD profit as well.
