BIP 100 is awful, if its adopted its the death of Bitcoin for me at least dump and buy Litecoin maybe?
But then if BIP100 gets adopted purely because of miner majority even if the userbase doesn't want it, it would actually highlight a major flaw in cryptocoins, namley that hash power would be able to force rule changes against its users, which is far more dangerous than a 51% attack, it basically means you can never trust in the rules of any coin anymore (so no, moving to litecoin isnt the answer), for they are no longer this stable set in stone neutral thing that was so attractive in the first place, but a thing that can change due to the will of a few.
I dont believe BIP 100 will be adopted simply because of hash majority, but if it is then Bitcoin is flawed and the next big thing would be a coin that has a voting mechanism that goes beyond just hashpower some way of seeing what nodes relate to what entity's so consensus on any update can be be gauged over a wider spectrum.
