Siacoin is a coin for a decentralized cloud storage and has been around since 2016. It can not be said that its a new coin, but one of the veterans in the cryptocurrency market.
At the same time the price of Siacoin remains very cheap and currently, SC/BTC is traded at 130 satoshis! Obviously not many "veterans" cost that cheap and perhaps this could be a very interesting investment opportunity in 2018.
On the Siacoin roadmap for 2018 it states:
"Our goal: Sia becomes production-ready for cold storage, begins to be used by companies, and introduces file sharing."
If everything goes according to the Siacoin plan, this could trigger a strong rally in price, as not only people but potentially large companies will use Siacoin services for the cloud storage.
Looking at the chart. Siacoin continues to reject the uptrend trendline and currently found the support at 88.6% Fibonacci retracement level. While the support is holding the next wave up could result in a rally towards the 430 satoshis resistance. But/when/if it will be broken, the upside potential could be enormous.
