I dont think privex.io is the best host.
It could happening again that the blockchain goes offline.
You think now, this is not possible?
Imagine, i think ~75 percent of the steem-blockchain is hosted by privex.io if they have any problem or get ddosed, the other ~25 percent get overloaded and break down.
I think this is the reason why the blockchain was offline some weeks ago...

This is just my oppinion. sorry for bad english
I vote for you as a witness!
