Prisoner's dilemma at work here...
Multipool payouts are not what most miners expected, causing many to stupidly panic sell and point their miners elsewhere, causing the multipool(s) to have less oomph, causing less BTC -> BC buying power (which by my simple calculations maybe is now only buying 7 BTC worth of BC per day using roughly 400 MH/s scrypt, 350 GH/s sha estimates).
If miners were more organized (and rational) towards having 1 dominate competitor to BTC (fuck Litecoin) and stayed put pointed towards the BC multipool(s) they all would have benefited...more miners = more oomph = more BTC -> BC buying from the multipool(s)= your accrued BC are worth more and more as prices increase and eventually miners have large enough profits to upgrade mining rigs to gain even more BC and so the multipool(s) buys more BC and the price continues to go up. It's a fucking positive feedback loop and we will all win.
Rambling-on Alert
Imagine being able to someday tell your grandkids about how you still have BlackCoins you mined/bought when it was going for 3 fucking pennies per coin in 2014, and imagine them saying in disbelief "grandpa, you're a lying sack of shit" and then you show them your BC address and absolutely blow their minds. Today's baby-boomers/grandpas had stock certificates, baseball cards, stamps, coin collections, etc. when they were young, which weren't worth much then, but fuck did those things accrue value up to today. But thanks to third-world countries now being able to make (or forge) just about any physical thing under the sun, our generation will not see any equivalent physical items becoming valuable collectibles 50+ years from now.
However cryptocurrencies, and specifically those cryptocurrencies which survive/thrive/flourish in the coming months/years/decades, are going to be the stocks, baseball cards, stamps, coin collections of this generation.
Anyhow, who knows if miners will ever rationalize-the-fuck-up and come back to BC's multipool(s), but them coming back or not is all that matters right now for BC to survive/thrive/flourish with BTC over the coming months/years/decades.

Well, except the actual economic principles of the multipool are kinda flawed atm.. That is, until they are as profitable in terms of (btc => bc)/hashrate. If miners can go to another multipool where they will get more btc for their hashrate and therefore can buy more bc per their hashrate, then they are actually providing more buy support (assuming they spend all of the mined btc on bc). the only advantage of the multipool is psychological- which can have a profound and hard to estimate/predict effect, though!
