It seems that there is someone out there with an enormous amount of hashing power.

This screencap is taken from Minergate.
So there is at least one person that controls more hashing power than the whole Bytecoin hashrate. This makes Bytecoin quite insecure to use at the moment (not to speak from the other low hashrate cryptonote alts).
Also since there is a pool with more than 51% hashrate, we are effectively using a central authority, not a decentralized network.
I would advice everyone hashing at bcn.extremepool.org to swap to a smaller pool for the good of the network.
Maybe the main reason for that is the few pools operating and lack of p2pool.
I was thinking on moving to this coin to test, but I better not.
