Today for some reason everything is down. Kind of like what happened last week with the entire internet being down with the DNS attacks. Today I think it has to do with the ZCASH launch. Bitcointalk was down earlier today also.
Yep, seems like a DNS issue - probelms on bitcoin talk, yobit, SD and others - there is obviously some effort buy criminals to buy or dump some coins without anybody else being able to report it or access the exchanges.
I have no idea why they are doing it. I don't think they benefit anyway by hacking Bitcointalk. And there is also alot of liquidity right now to sell Bitcoin. However it looks like it might go back to yearly highs.
