sorry, I never replied to the other question, I'm no expert, but the ROI is definitely going to decrease very quickly in the next few weeks as the larger 100\GH\s and TH\s machines roll off the lines.
I read today a estimated 30% difficulty every 10 days....
maybe think about buying mining equipment to mine alternative coins
or get into trading currencies and mining by profitability and value
or by bitcoins and hold onto them (probably the safest advice)
ok thanks!
but what about the other two questions
2. will this machine have any chance of giving a ROI? (about 360$ with taxes, etc.)
3. every post i read, says the difficulty will keep on increasing at a MINIMUM of 55% per month! is this really possible? wouldnt it make every miner a piece of garbage within a few months? dont you think at some point of time the difficulty will remain constant or even fall?
thanks a lot!
