So Bitcoin is thought to maybe go PoS after...
Thought by
who? Links to the sources of your speculation please...
Certainly not by anyone who understands what Bitcoin is and what it brings to the table by using PoW. It will be a very cold day in Hades before Bitcoin is changed to PoS. More to the point -- applying the required fork means it would no longer be
BTC and instead would become just another Piece Of Shit altcoin.
