don't be naive, only because price changed so fast these months doesn't mean that it will continue like this. I'm sure that price will be 7500$ by the end of 2017 but 10k$ is just too much in my opinion, changes like this requires time and more people interested in bitcoins.
Wait till this December to find the value to 7.5k USD or more than that. From the past three I noticed that bitcoin price started increasing in the time of Christmas and New year time.
If the supply and demand increase in the bitcoin surely you will be find the better value in the chart. This theory takes the bitcoin value with the steady growth.
