My Opinion on SiaCoin I would be giving my opinion as a web developer and website administrator as well as a trader-cum-investor.
SiaCoin is the cryptocurrency which is supposed to be used in Sia Network, a decentralized cloud storage based on blockchain technology.
There is NOT many but only a few others which are working on same technology of decentralized cloud storage which are Storj and Safe Network only.
Sia is in pre-release mode, and will be up with their v1.0, first official release on 28 June, 2017. They have been working on this since 2014.
What made Siacoin so popular suddenly? It’s cost. Sia aims to provide 1 TB storage at just $2 per month, cheaper than anything on earth currently. As the administrator of huge data-handling website, this is seriously cheap. That too cloud storage technology where noone can delete or have your file without permission. No stupid copyright, no trolls etc.
Rest other network have been released, Sia is the only one which will release its first version. Hence for now, it is considered to be good investment from monetary as well as technology view.
