If there’s no energy for BTC, there won’t be energy for anything, in which case you won’t need to worry about BTC or ETH.
whenever you are discussing a topic on a particular board then it is very patinent to pay attention strictly on the board requirements areas of discussion, we cares about ETH here, this is mainly bitcoin and we focus on everything partaining it.
OP your talks goes much on relating PoW with PoS if am correct, but am not yet clear about which side you really belong.
There is an ETH propaganda topic in this forum with the title “BITCOIN IS DEAD!”.
everyday comes in with different people with different and contrary talks about bitcoin even while on this forum but we cannot give an attentive hearings to them because the forum here is all about bitcointalk but we must consider interest on areas the serves a benefit to the network and also perform the function of ignore button on users not getting it on point.
