So Satoshi Bitcoin will split to Chinese Bitcoin and Blockstream Bitcoin.
If only core developers were capable/motivated/competent to find a solution to increase block size so that people can continue using bitcoin without paying ridiculous fees and insane confirmation time.
Anyways, if there is a split then BTC will not survive as BU needs 70% miner support and if there is 70% support, even less than 50% of those miners can do a 51% attack on BTC, so BTC will need to change their POW as they are planning now, at that point BTC will no longer be BTC but just another altcoin, and a technically inferior coin to many other altcoins.
So why wait for everything to fall apart when the only option is to choose an altcoin and start using it.
If there is a split, the price will drop but one will fade away and the one that survives should still do well. Won't we (Bitcoin holders) have an equal number of each version? I think we may be okay in this situation, but it is good to diversify.
