We are experience of fast price increase this past few days and until now and i think this is because of segwit added..
Or this it is just nature of bitcoin the same as last year price increase if we compare the same fluctuate and i think more price will reach soon..
I am beginning to think it was because of segwit too.
If it has anything to do with Chinese influence then that affects bitcoin because of their large user base of bitcoin technology.
I think its because of ZCASH and ICN. These three attract a lot of new users from the outside and because of that Bitcoin demand rises as depicted on the exchange sites. It will probably continue until the real value of these coins stabilizes but this is just my opinion though.
