In a perspective in 2 - 4 years we are planning to move to DAG, as IOTA and Nano have - they have no mining, so do not buy systems for CPU-only mining of Binarium. Useful calculations mainly will be performed on GPUs.
Honestly at that point I do not agree, I do not think it will do well to the crypto to enable the mining with GPU, as I do not think it is fruitful to do it PoS, the only way that would be profitable is if it did not have too much difference the mining of cpu and gpu
