The main question remains - whether "decentralization" is really something that people value. I would not be suprised if people stay at Dropbox/Google. This is something I started to notice a while ago - people involved in crypto tend to overestimate decentralization. And crowd.. just does not care. So if there is no demand for decentralized storage - storjcoin price will go down. If there is demand - it will go up. Doesn't really matter what early adopters would do.
Even if people don't value decentralization, increased redundancy and higher privacy, they will value cheaper storage!
I don't believe the majority of the public is currently aware of the need for decentralization or privacy, but when they find out that it's faster and cheaper than the competitors they'll jump on without thinking twice - i.e. they'll do what's in their best interest without even being aware of it.
