If we run two concurrent forks then anyone on the failing fork will be left holding a wallet full of worthless coins and any transactions that occurred on that chain may as well have never taken place.
So what, you also hold the identical coins on the valuable chain. Awesome!!!
Investors hate uncertainty and just the proposition that the chains may be split could destroy the value of either.
Who fucking cares about 'investors'. We are trying to build something awesome here. We are not trying to please speculators from China. Fuck them. Let get to work and build great things with no regard for stupid fucking speculation.
Better to use testnets or another shitcoin or something and leave the main network alone until we know what's best.
LOL - 'testnets' The whole fucking thing is a test net. Bitcoin is a test. Let's do this for real. On the 'real' net.
