Hello,
I have a 7mh/s gpu. I want to mine some coins. My question is how does this work. If a coin is worth 1$ and i can mine a max of 100 coins with my gpu. Does that mean that i will get 100$ a day?
Thank you
The mining pool coordinates the workers. Think of it like a lottery. If you and your friends all buy tickets in the lottery the group has a better chance of winning. To be fair in the lottery example everyone should be rewarded proportional to the amount of money spent on tickets. So if there are 20 tickets for the pool one person purchased 10 and two people purchased 5 each - if one of the 20 tickets win the person who purchased 10 gets 50% and the other two get 25% each.
What a mining pool does is function as a coordinator for all the pool participants doing:
Taking the pool members hashes
Looking for block rewards
Recording how much work all the participants are doing
Assigning block rewards proportionally to participants
Miners mine differently by running pool software instead of the bitcoin client and just performing hashes for the pool
