The magic I saw was wasted time and tiny tiny tiny payouts... you can see my posts to their threads on Reddit from weeks ago.  They're hashpower is a fraction of Hashcows much less Middlecoin, and Hashcows has a hard enough time of taking on profitable coins because of their hashpower.

What many fail to realize is that going back to early 2013, Middlecoin's biggest strength has been H20's ability to do private or (hidden) selling of the altcoins while Exchanges like Cryptsy are down.  That's why whenever the Unexchanged value is rising like it is now, I'm rubbing my hands together in glee rather than worrying...  The other pools don't have the trading connections H20 seems to.  

I've been on Middlecoin on my current account since August, and another account from earlier in the year into July.  I was parallel hashing on Hashcows since they started, but jumped back full power on Middlecoin when I saw the Doge run-up during the Holidays (Middlecoin was 4 days ahead of any multipool in jumping on Dogecoin and then sold to starving buyers when Cryptsy was locked and down for Doge making everyone including Hashcows scrambling).

When Wafflepool started a few weeks ago, I put some power into them to try them out... pathetic returns and buggy coin handling.  Tried them again a few days later, still crappy.
Put in a few requests and posts on their Reddit threads... saw similar experiences to mine with other users.

So what has changed in the last week with Wafflepool to make it magic?  Do they have the ability to sell when everyone can't like Middlecoin can?  I'll go where the profit is... and I have done full parallel hashpower testing.  Middlecoin still takes the cake.
