Slush makes 1500 BTC daily with a 2% fee, that's about $13,000 a month. That could buy some serious bandwidth
So Slush's pool is solving 1500 blocks daily? That's why difficulty keeps increasing every two days....
And I'm glad I'm part of it, i get about 0.02 BTC out of every block, giving me a profit of 1500*0.02=30BTC per day! Not.
But you probably meant 1500 BTC per month, which would fit the rest of your message :-)
1500 BTC daily is 30 blocks per day.
