welcome to bitcoin.
this rise is a tiny rise because it is only a little less than 7% rise. if you take a look at bitcoin's price history you can see rises like this usually happen in matter of minutes not a day. these days we are very slow when it comes to rising, a part of it is because the number is big! and another part of it is because market has grown so big in the past year than it is much harder to move around, both up and down have more resistances.
