I actually sold it all for a few satoshi profit and flipped back into Monero back in April. I made half a bitcoin profit at most.
If you have followed Sia you may know that the recent price hike was all down to Yunbi (a large Chinese exchange) listing Siacoin next to a small selection of other alts. So, consider what will happen when 1.0 is launched ...
Based on that I'd guess "what will happen" (with respect to price) will depend more on what large Chinese exchanges do than on what versions are launched.
If this was a typically vanilla altcoin, I would agree. But there is a significant difference between SC and a "payments" coin. SC will not compete with other coins to become yet another payments protocol. Rather, siacoin serves the purpose of mediating payments for file storage. So, I do think that the 1.0 launch, with an consumer oriented UI and API for 3rd party developers, will boost the utilized storage volume, and therefore also Siacoin price (since renting storage on the network requires the uploader to pay with Siacoin).
