Bitminter had been mining for 9 years. When it shut down there was a lot of experience and in-house developed software that seemed a waste to throw away. Now that is part of XBTO Digital instead.
Mining has changed a lot. From individual mining to mining pools. From CPUs to GPUS, to FPGAs, to ASICs. From individuals mining at home to companies running big mining operations. From any individual being able to start a mining pool, to pools run by companies. Companies that have their own big mining operations, or is otherwise connected to one. Otherwise the pool won't reach critical mass.
Bitminter could not survive how the mining world changed in recent years. So now we bring the best of Bitminter to a bigger and more viable operation.
