This release is so big that the worth of the coin is shooting up even when the markets are plumeting around.
Sia is an new form of cloud service with far cheaper prices than amazon or dropbox. If it becomes mainstream i can become an multi billion dollar coin.
I think after the market correction Sia coin will boom. I would say if Sia gets one major contract it can easily shoot up to 0,5$ (its now at 0,015$).
I am a long term holder of Sia. I really see a future in this Coin. They have a concept and an good developer team.
Prices were on 0.02$ not even 4 days ago! Maybe one of the best Coins to buy next to Steem right now.
