I read that MetaMask has blocked the EOS crowdsale citing stability reasons. So today's period may close with a better price than Period 0, and I think the blacklisting is why.
5 hours to go at this time.
It'll be interesting to see what happens going forward. I don't think anybody foresaw an issue like this.
I should add that I just read about MetaMask blacklisting the EOS crowdsale in a comment here at Steemit. I haven't seen anything official from Metamask, but I'm curious now, so I'll see if I can contact the developers.
