Franky1 is the biggest advocate of this idea in the forum. I respect that, but it is very debatable. What if Bitcoin Cash increased its block size and doubled its monetary supply? Would that "bilateral split" idea be easy to accept? I believe it won't.
If it increases the block size and total supply will make things worse. If this happens, will the price drop by half? And who are the owners of the supply of additional supply? Who owns it get benefits from this? Any reason I believe in this?
if it doubles the total coin supply. then deflation is dead. mindset changes from "guaranteed limit" to "if they done it once they will do it again"
trust is lost and people dont value the coin anymore as a store of value
