Good question. But I think Sia's aim are more business oriented and they're not concerned about siacoin valuation. The business would automatically establish value for the company, especially if large deals come out in the news. So this to me is a proper investment.
But marketing to businesses is definitely important so I'm also curious if there is a budget for that.
Our goal is to get as many long term users as possible. I think that one of Nxt's biggest shortcomings was that most of their code catered to short term uses. For example, the original Sia crowdfund was actually performed on Nxt, we used it for a short period of time and then we withdrew - our needs for Nxt were temporary.
At the moment our marketing focus is more on getting press hits and organic word-of-mouth growth. The user experience is still choppy, and until we've tuned that up I don't think it makes sense to chase mainstream users - they will get turned away as soon as they download.
On the other hand, we are making attempts at getting press coverage in places like CoinDesk, CoinTelegraph, etc.
We're definitely working hard to grow the ecosystem.
