Currently its a great buy time due to the bloodbath today.
Currently cloud storage services are mostly centralized and the data is stored on a third party server. With Siacoin, the storage would be decentralized as each user would contribute their own share of resources.
You may think “There are plenty of decentralized storage projects, is Sia any different?” It is true that Sia has its competitors, Storj and Maidsafe are just a few. However, what sets Sia apart lies in the intricate details relating to maintaining the decentralized ecosystem.
I'm also currently working on a way to figure out how is possible to provide space for the cloud and get paid to give away free storage. Sia coin guarantees payment with a blockchain contract for the host.
