Siacoin genesis block was June 6th 2015, so this coins is over 4 years old, a very long time in crypto.
Sia provides a decentralized cloud storage, where you can store your files and data on the cloud with privacy and without the risk of being kicked out or banned from big corporations like dropbox, google or Apple.
Now the Sia tech team is launching a new service based on their cloud; the opportunity to stream directly to Plex, Kodi or any other streaming app; SiaStream uses Sia to provide low cost media storage and fast video streaming. You can signup at siastream.tech to be updated on the public release.

Sia is fueled by $SC , a coin that has been in accumulation right around 20 sats for a few months now, but has pumped already many times in the past, going from 40 satoshis to 670 in a span of 3 weeks at the end of the 2017 altseason.

Will SC be able to reach those levels again and jump into the top20 of the market cap? I'm not sure, but looking at the daily chart i think there there is a very good change for a quick movement up to the 124 sats resistance.
Time will tell, but these fundamental news might be the right catalyst for a move!
