It seems that moin is going to be delisted from c-cex. It's a shame that such a good coin has so low volume

Hi guys i am not really clear with this scaling problem but concerns me a little, and was wondering why adding POS to bitcoin isn't taken in consideration? I mean everybody would benefit from adding 1 pos block in between 2 pow blocks. Magically we could keep 1mb blocksize pow miners would have the same rewards but at the same time more frequent blocks would lower the confirmation times and also technically we would have double space for transactions than we have now.
