The results will be decided on August 1, let's wait together, however, one thing is certain, BU will not be recognized. Segwit and core will be the only two options.
did i miss something? segwit IS core, isn't it?
I'm thinking the real solution will be a better UASF a while later, or a compromise involving SegWit + 2mb implemented by Core.
If neither of those things happen, we might end up with a half-hearted attempt to implement LN on the current Bitcoin, and a pathetic display leading to a slow takeover from alts.
The question you should be making yourself is: are all those alts attempting to takeover Bitcoin really decentralized?
ETC - yes.
Litecoin - yes.
Monero - yes.
Tertiary alts (e.g. Byteball) - yes, unless they're built on the Ethereum network or they're too small to be properly decentralised (or they're shitcoins with a huge premine/instamine).
To dismiss altcoins as useless is basically ignorance, because even when being newly created they can develop innovations, so it doesn't necessarily mean that they're mutable.
I'd say Bitcoin will still be quite relevant when no scaling is implemented, but it would be a half-hearted attempt at relevance and would mainly be propped up by HODLers and people "diversifying" their cryptocurrency portfolio into several coins.
