on Mar 15 MC went from balance of 87 to 74
That's not correct. That 74 on the chart is some sort of a glitch, if you look at the actual scale where the next red line starts it's closer to 50. The reason I'm nitpicking here is that I know for a fact that my payout that day was not 0.0013. There is no doubt that middlecoin is way off its heyday, but it's not as horrible as it may seem. It just had a large payout a couple of hours ago, and it's still sitting on a mountain of unexchanged coins, which might be worth something.
Yep, MC is hard to estimate with all the unexchanged. Sort of a rollercoaster. It will be interesting to see how it all plays out. I'm not ruling out going back to MC. They still have a lot of hash power which of course is more luck towards being successful.
edit: it actually makes me wonder if there's any trading benefit to keeping a certain balance of btc with various exchanges. I know with stock exchange services you get better flexibility and options if you maintain a larger balance.
