difficulty up 250% was just 72K yesterday.

yep

hard to find new block... We need more hash.
The difficulty of Bitcoin Z has decreased again today. We should take advantage and try to mine it as much as possible. It gonna be pumped in the future. I am also waiting for more good news from developers such as roadmap, whitepaper, new products, new features, etc. Please look at what ZEN cash has got recent days.
