Also BTC will not be used by billionaires only, that's stupid, people will demand changes so bitcoin cannot be used only by a handful of people on earth. If it takes UASF then UASF will happen so segwit + LN can happen and everyone can use bitcoin, additional blocksize increases will come too. Nobody will support the "billionares only blockchain", that's stupid.
Sorry you can't do anything to stop it:
Cry and scream all you want. You are wasting your time fighting what is inevitable.
Soon you will realize this. Go ahead and try. My popcorn is laughing.
It's as easy as UASF + PoW change with a new solution such as randomly changing algorithm to avoid efficient ASIC stacking.
"BillionaireChain" used by 2,000 people on earth will be seen as a joke by the rest of the population and it will no longer be Bitcoin. Progress will move on.
