Or the days before that, when a single GPU could easily make 0.01 BTC per day. That was kind of nice.
No before that a single GPU was mining 1 a day, so 50BTC + fees from a 5870. Of course if you bought Bitcoin instead of the 5870 back then you would have had thousands of BTC
Unless you have a time machine you can't go back to those days - you can only focus on the current time.
