now in this year mostly people know about bitcoin instead of last 2 years. so mostly people buy it and mostly people invest it, so just like that more reasons behind the rising the price of bitcoins.
The slow rise can't be a whale movie. so I suspect more people/companies buying bitcoin creating a demand which triggers this small rise. Normally this can go on for a week with ups and downs and the price will settle then.
Nothing bad is happening, in my opinion price will rising sooner or later..
