It's been going up for a year based on Chinese investment and ongoing adoption. I see nothing new?
there are many new things going on. like the hype of US election, the India and how bitcoin price has been going to the moon there, and some other countries starting to find out about bitcoin. these on their own may not be so significant changes but the rise were not that significant either.
and the biggest one is Segwit in my opinion which looks to be going well.
I think that the reason is pretty much more people realising that bitcoin is a good investment at this stage with such a low price. More Chinese investors as well I guess. Volume has been consistently over billions of dollars on major Chinese exchanges.
Trump could also be a reason.
the volume coming from China is always big, so that is nothing new.
and besides people don't just wake up some day saying i got to get me some bitcoin! it happens slowly and one person at a time unless something big changes and i was looking to see if something big has changed!
