Curious - did you sell BTC, or buy BCH to achieve this (50:50 value)? Or do you mean you have quantity x BTC and quantity x BCH, as distributed(85:15-ish value currently)? Reasoning?
All percentages there are expressed as the current Bitcoin BTC Value of the Alt coin, i.e. so if total portfolio value is 10 BTC then "40%" would be 4 BTC worth of Monero, 15% would be 1.5 BTC worth of BCH, etc.
The BTC/BCH situation is: actually MOST of the BCH is what I got "free" from the August 1st fork, but yes I did "flip" a portion (some BTC and some Dash, maybe some MaidSafe too, I forget) into getting more BCH a couple times since the fork, when the ratio was higher like 10 to 1 at first, and then again when it was like 5 or 6 to 1, I think it was.
So overall -- now that the BCH price has been reasonably stable around $600 to the BTC price reasonably stable around $4600... crunching the numbers yesterday, my total of each has now just happened to land on 50-50, i.e. the BCH (valued in BTC) is worth just about what the remaining BTC is at... so 50-50.
I'm fine with this 'cuz it means I'm preserving my BTC in BTC value, so far, if nothing else changes (ha!) but if the Bitcoin Cash people are right, and BTC will end up in a Death Spiral then my "new bitcoins" stash will be multiplied several times... only at risk of a *portion* of my starting BTC stash IF the SegWit people are right and Bitcoin Cash is the one that eventually withers away and dies.
Who knows WTF will happen? I certainly don't, LOL, so this seems a reasonable hedge position to me, for the time being, again until something ELSE changes.
P.S.
Nice... so "good luck with all THAT" to the Dashers, LOL. And, since I just clearly stated publicly that I've dumped all the Dash I used to have, of course in order to fully do their job properly, any of our Friendly Neighborhood Federal Agents reading this will now certainly make sure that my name is REMOVED from this wonderful watchlist... right? Right? Hmm...
