It seems likely that users (and companies) will just call whichever one they prefer Bitcoin, and that there won't be a chain which everyone just simultaneously agrees is Bitcoin because the support for each chain won't be so overwhelming that the other becomes less relevant.
Assuming miner/exchange cohesion continues:
What do you think the Bitcoin as original Bitcoin use case(s) in 2018 is going to be. Do you think that there will be exchanges say in the US for that?
Peer-to-peer?
merchant agreements?
And how long is it going to take to get the new POW hash implemented to protect this coin from mischief? or is that not necessary?
And without the POW hardfork how is difficulty going to adjust in any rational time with the loss of the >90 percent of the miner hashpower?
Thanks for your comment. This issue of relative chain support is exactly what I am trying to understand. I am having some difficulty seeing how the original chain keeps on trucking. But I certainly don't have a comprehensive understanding of the existing food chain.
