- Decreasing chances for small pools to create blocks and attract more mining power to grow. With no reward on mid-size pools all miners should prefer to mine on big pools with better expectations for return on investment, rather than supporting new pools.
I stopped reading here. This isn't correct.
Expected return is not increased by using a larger pool. Mining is not a race, it's a random lottery.
But I understood that if a pool has more people it has more chances of winning the lottery, is this incorrect?
