Topic: How much CPU time is needed to mine 1 bitcoin? (Read 147 times)
Typical high-end computer graphics card will give you a hashrate of a few hundreds of MH/s. Let's say 500 MH/s (that may even be optimistic if you are using a laptop graphics card with no specific optimization or tweaking). According to a online mining calculator this gives you a whooping 0.00000629 BTC per day. Which means it would take about 435 years to mine a single bitcoin. And that computation is not even worth anything because it assumes that the difficulty will remain constant, which it won't.
