you shouldn't even begin to compare ethereum split with bitcoin's possible split.
ethereum is centralized and they have millions of coins at their disposal (some speculate about 70 million) and when the split happened they started dumping coins on ETC market to prevent its price to go up and then used the funds to put up buy walls to prevent ETH crash.
there is no such thing in bitcoin!
What is ethereum? isn't a blockchain capable of handling tokens and smart contracts? now what is ETC mate can you tell me?
Did ETC miners also split the ethereum foundation in half and if so then what is stopping people from copying the entire thing and
Have their own version of ETH? at least with Bitcoin even with two blockchains both of them will function the same capable of transferring value.
