The order book on both exchanges look rather bad.
I don't think it was a good idea to add BTCZ that soon to Whattomine. Now that the price went down a lot of small miners went away but there are still some big players.
Personally I find this rather interesting when i.e. compared to the HUSH network hash rate.
I am fine with fewer miners and lower difficulty for a while. It's an opportunity to mine some more before the price rises again and they rush back in.
What I meant to say is that on suprnova the number of workers decreased considerably but the hash rate proportionally less. This is an indication that only small miners left. I made this observation multiple times.
