The less crowded a pool is, the more shares per block you will get but the more crowded a pool is the less it takes to find a block. So can we make a mathematical equation taking into account the hash rates, number of miners and current and estimated difficulties in two or more pools to judge which pool is more profitable and mine in that pool?
Secondly, i know this is an extremely newbie question but is there anyone who would mind telling me how and why the difficulty changes, rises or decreases with time?
Thirdly, I have 3 Asus R9 280x on my rig. I mined different coins, although it was one week only, before. All of them was scrypt ones and I got ~750Kh/s per card. Why does my cards mine at ~530~550 Kh/s per card on my rig when mining BDC? As Cloudpost has the same cards I know this is normal but want to learn why.
Lastly, I want to thank to and congratulate Nikolas and colleagues for first thinking and than coding a coin as different as BDC. I hope it will be very beneficial for all who mine it.
