Did a lot on research on Sia, StorJ and Maidsafe - Sia is my favourite by far.
- Great, transparent team with good roadmap (Seriously, there is no other project-lead with such great community interaction)
- Nameworthy investors backing the project (Li Xiaolai just gave them a 400k grant to expand their team https://sia.tech/2017grant/)
- Mineable, no ICO
- Upcoming ASICs to strengthen network
- Rising development on top of the Sia network (eg. MineBox with HP cooperation)
In my opinion definitely a Top 10 coin in 2018 - I can only recommend to check out their reddit /r/siacoin.
Are you know with an altcoin still cheap as Sia and can mining GPU, when have Asic mining is bad ways and making the price can breakdown by inflationary? And we not know Siacoin how many coin can supportly on market, not have limit and can creating everytime lol
