Kin wasn't sold to any Canadians or Americans in the ICO, but they are probably free to purchase KINs from the secondary market, which probably is good news for investors, as most users of the Kik app are based in US and Canada, once the adoption or launch of the Kin coin on Kik platform is done, there should be an initial demand from buyers from these countries while all the owners are from other countries, creating a surplus demand.
But will have to wait and watch. So current investors will have to hold their KINs till the launch of the Kin coin on Kik, to see significant returns on their investments.
Until then the Kin will hover around or below its ICO price until its a usable currency on one of their platforms.
