There are various topics related to how Bitcoin transactions can be used effectively to reduce their power consumption needed to process each block transaction. In this regard, many have said that we need to improve our electricity source, but in fact, improving the technicalities of bitcoin in its internal coding frameworks is quite easier and more efficient. We could also add further updates to help open up opportunities for Bitcoin to be widely accepted worldwide. So i believe a lot of development this year will be focused on the mining changes.
