I don't intend to be a naysayer, but people should maintain realistic judgement. I see a good chance that lots of early adopters will feel comfortable selling off their original 10,000 SJCX when the full network goes live.
That is one possible scenario, that need to be considered, yes. On the other hand, the early adopters might have a need for redundant, secure, online cloud backup too, so they might use (some of) their holdings to pay for the storage. Or only sell of part of their holdings, and keep the rest. We have no way of knowing, really. But sure, one possible scenario is price drop when storj goes live. Another possible scenario is a price increase, when people realize the full potential of the project. Compared with the market cap of other coins, storj has lots of room for increasing.
