well turns out i was right about 300 blocks 
anyhow I doubt devs could reduce this halving time, because they would have to fork it, but it's never been done, and i would suggest
not to fork it in the future, halving time is good and clear, each 100 000 blocks and that's it.
By the way i cannot believe my eyes that somebody is dumping, it's so rare now, it does not make sense. Now it's 5 more profitable to buy UNO then mine it, but i'm still leaving my s1 antminers on UNO to make sure network is secure enough.

I have no SHA256 miners, but I would do the same. Thanks! UNO will move up eventually.
The most probable cause for the dumps are people who bought when BW made his announcement, expecting a pump. They are now panic selling as UNO didn't move as high as they expected ("only" +30% or so).
Another possible reason: there was a lot of Wolong-taunting around the announcement. Maybe he or some of his associates still got some UNO left and dump out of spite. Maybe its a new whale that isn't done accumulating, who knows.
There's definitely a lot more sell pressure now than there was before. My low buy orders get hit a lot more often compared to before the announcement.
