Sweet! This is pretty much exactly what I've been saying since the flare-up near the beginning of 2015 and I'm happy to see some confirmation (though it's not exactly rocket-science and I'm sure that other's have thought up the same thing.)
Since you are a master at mining tech, could you comment on my thesis about mining:
For simplicity's sake, lets say that there are only two chains (though I expect a possibility of many more when the shit hits the fan...) 'Core' and 'XT'. Let's also say that neither one takes special actions to substanatively change any protocols or 'monitor and screw' the other. Let's also stiplate that miners behavior will approximate market driven principles (nobody hires them as mercenaries and they don't have strong political beliefs.)
Say Core market value is $100/coin
Say XT market value is $200/coin
I would expect that difficulty of each chain would adjust to how much mining effort was applied to supporting each. Thus, a miner would mine twice as many coins on Core as XT for a given total hash input. I would anticipate then that the mining power would approach a ratio which was represented by the market value of the respective coins.
Since I do not fully understand how difficulties are represented in chains, I don't know if I am off-base in this thesis. Any thoughts?
