The big swings in difficulty and overall network hash rate suggest to me that there is an auto switching pool with LOT in its makeup. Anyone aware of such a pool? Im assuming they must be using the coinedup exchange rate in any calculations. Never seen an auto switching pool mine on a coin that isnt at least on cryptsy. Very strange. Dont know whether its good or bad, as its popularity must be going up (driving the price upward), but also if there is an auto switching pool, it will no doubt be dumping at regular intervals on coinedup, which will keep prices down.
imho, the auto trading multi pools are doing a diservice as the constant dumps in large volumes just drives values down across multiple coins.
I'm not sure that's the case here as they usually bring in multiple GH/s when they switch to a coin, and I haven't seen the network hash rate soar quite that much.
To your last point, yes, and the sooner the concept stops working the better. Whether that's because it becomes unprofitable or because coins develop self-defense mechanisms I really don't care. Take WDC as an example. Good coin, USD banking in beta, solid dev team etc. The auto-pools come in and double or triple the network hash rate, double the difficulty or more, then dump tens of thousands of coins on the exchanges leaving people who are mining because they actually believe in the concept with the double whammy of lower prices and higher difficulty. Why the people who use these services can't see that they are actually contributing to lower mining profitability for everyone, including themselves, I have no idea. Math is hard I guess.
