This is the final step after you have chosen a pool to mine in and joined it. The difficulty increases with a higher hashrate and decreases with a lower one.
It is advantageous to have a high hashing rate, as it increases the security of crypto networks.
Bitcoin mining pools are needed because all miners, except those with the largest and most powerful equipment, find it difficult to locate blocks as individual miners.
A crypto-mining pool pools input from miners located around the globe and collects their hash rate. This allows them to mine at higher levels, which increases their chances of breaking blocks.
The rewards are divided among the mining pool members according to the processing power they provided after each block was processed.
