Well, bitcoins might be less accessible if most of the people would not want to sell them, the price would go up even more dirastically. In terms of access, they still will be traded on exchanges so if you've got fiat, you can buy it.
According to statistics, in 3 years it will be very hard to have atleast one bitcoin and this will lead to drastic increase of bitcoin price. So, this is the right time to accumulate, so do accumulate as much as you can.
