Difficulty jumped from about 0.01 to 0.014. That's 40% more which means much more new miners. Unfortunatelly they all go to one pool 
are you saying the pool cant be trusted? i dont think you need to worry, if UTC become more profitable to mine, other profit-switching multipools will switch to it or add the option to mine Scrypt ChaCha
I doubt there is anything nefarious going on with the pool. But I have to admit it did lower my expectations when I found there was only one pool with almost all the hash rate. I've come to find the this coin is held up by its community of loyal followers. One of the few coins that's actually worth holding onto.
UTC already pops up to the top occasionally with Kbombas Profit Calculator tool. Which could explain some of the new miners.

The only problem with having profit-switching multipools targeting UTC will be a drop in price as it gets mercilessly pounded by the selling from miners dumping it.
Again, I'll offer up my pool. http://utc.tumblingblock.com. There's 0% tax. There will be orphans until a decent hashrate achieved. At 70kh/s we were getting orphans, but that's a very small percentage of the hash rate.
I just thought that all new miners are going in one place. 
maybe we have to except it: Welcome to the Wild, Wild West of Crypto World !
