Bitminer was one of the oldest mining pool that came just two years after the emergence of Bitcoin as a platform where miners can mine Bitcoins. The mining pool has been shut down since last year but their website is still active for all their miners to withdraw their assets.
I will be given this mining pool a three star rating due to their high and optimum performance and rewards when the pool was still operating,but over the years the pool wasn't able to keep providing such unique rewards to Bitcoin miners. After Nine years of operation the pool is shutting down all its operation due to its inability to meet up with customers demands and expectations.
Bitminer has proven to be a trusted mining pool with its high level of transparency and trust to miners from its emergence to the time it was shutting down all operations.
