I think that only a few percentage of people would sell their bitcoins to fulfill their wishes.Still,most of other people would just hold their bitcoins as they would gain more confidence on seeing bitcoin's price rising high.Mostly,old investors would not sell their bitcoins as they were the people who were seeing bitcoin's potential from its early stage.
Mostly,people will hold bitcoins in a long term basis and they would not bother about the short term price hikes.Some people will sell a small percentage of their bitcoins to enjoy the benefits of price hike.
The prices at which bitcoin is residing at present have further strengthen the trust of people in holding bitcoin for a long time in order to enjoy grand profits. Bitcoin is the fastest way of making money at the moment. Only those will sell off bitcoin who are in desperate need of money or are fool.
No wise person can ever think about selling off all the bitcoin he has in his wallet because bitcoin are evergreen in terms of profit.
