Have you considered the leveraged FUD effect of an immediate post-fork 300k supply dump into BTC core by Ver and god knows how much more by what other wealthy vested interests are behind him and BU™?
If it forks and the BTC/BTU price is manipulated immediately to artificially make BTU the definitive short-term winner (even if only for like the first day), which I believe they have the financial power to do, the broader investing public will jump ship to the more valuable coin.
The net result of this being that BTC loses almost all its value in the panic, and BTU's value goes up and stays there for like 2 weeks till a fatal exploit is found in their bug-ridden codebase and then both versions of bitcoin have lost all confidence and financial backing and the whole crypto experiment is over.
P.S. I'm just sharing my thoughts. I'm not trying to upset anyone or cause panic, just urging everybody not to be complacent in the face of this threat. I am a big believer and investor in crypto, and I will not watch the trust in this game-changing innovation be destroyed in the eyes of the public for the next 20 years because of some hostile group of idiots trying to seize for themselves the power of a system made for the people.
