What is Siacoin?
Siacoin is the native token of Sia, a decentralised cloud storage network that launched in 2015. Sia was created by Nebulous Inc, later known as Skynet Labs, and it does away with the usual central storage company by running a peer-to-peer marketplace where people rent out spare hard-drive space to others around the world.
The network leans on blockchain technology and smart contracts to keep storage private and dependable. Files are encrypted, split into pieces, and spread across many independent hosts, which builds in redundancy and keeps any single host from holding a complete file. Siacoin is the payment used inside storage contracts and the reward that encourages hosts to stay reliable.
People hold SC to take part in this storage economy, whether as renters after cheaper private storage or as hosts earning SC for the space they provide. The token also reaches into the wider Sia ecosystem, and its supporters see decentralised storage as a practical alternative as the world's data keeps growing.

FAQ
Buying Siacoin: FAQs
What is the smallest amount of Siacoin I can buy?
You do not have to buy in large amounts to get started. Digital Surge lets you spend a small sum of AUD and receive the matching quantity of SC, so you can begin at whatever level fits your budget instead of a fixed number of coins.
How quickly can I buy Siacoin?
Most buyers are done within minutes. Identity checks usually clear fast, and AUD deposits sent with PayID often land in under a minute, so a verified and funded account can buy SC at the live price almost right away.
Can I sell Siacoin back to Australian dollars?
Yes. You can sell your SC on Digital Surge whenever you choose and receive AUD, then withdraw those Australian dollars to your linked bank account. There is no lock-in period, so selling some or all of your Siacoin is entirely your call.
What does Siacoin actually do?
Siacoin pays for storage on the Sia network, a decentralised marketplace where users rent spare hard-drive space from hosts worldwide. Files are encrypted and split across many hosts, and SC both settles the storage contracts and rewards hosts for keeping that space available.
How is Sia storage different from a normal cloud service?
Instead of one company holding your data on central servers, Sia splits encrypted files across many independent hosts. Supporters say this can work out cheaper than traditional providers while adding privacy, since no single host holds a full, readable copy of your files.
How do I check the live Siacoin price in AUD?
The live Siacoin price in AUD is shown at the top of this page and refreshes through the day. You can read the current SC rate in Australian dollars, open the chart for recent movement, or use the converter to price a set amount before you buy.
