You are right to the extent that the purpose of CannabisCoin is to facilitate getting medicinal cannabis to medical marijuana patients (medical cannabis patients?).
The Yes We CANN movement, however, is about getting donated medicine to those who can't afford it. For that CANN acts as a token to direct those donations.
This brings us to a dichotomy of perspectives. Altcoin speculators tend to be disappointed that we make no effort to pump CANN's trading price. Patients and their supporters are more interested in the community.
So, consulting crystal balls, what happens if?
Ideal situation: Bernie Sanders' proposed legislation gets up and and cannabis is removed from regulation. Likely, do you think? Probably not.
Worst case: Chris Christie becomes President and overrides state legislation by executive order, taking us back to the very worst of prohibition. Fortunately also not likely.
Likely case? Things go on more or less as they are, the Yes We CANN movement continues its quiet growth, philanthropic holders continue providing support for those who cannot afford it and altcoin speculators continue to trade CANN for profit.
Bottom line is that I foresee a growing use case for CANN, others may view it differently.
