It is actually a good time to think about this.
The fundamental problem with Bitcoin is that the rules can be changed. This happens all the time in the securities business producing massive losses. From my perspective it is actually only a matter of time. Lawyers are not paid to preserve the status quo but to turn things to the advantage of his client.
Thus every lawyer out there is scheming to print bitcoins at no cost.
Getting past that problem and it becomes a store of value in the same way Gold is. What makes gold work is how hard it is to produce. That still might change and then it is all over..
