Volume Bubbles Chart (1h)
Each 1-hour candle's volume is signed by its direction (up candles count as net buying, down candles as net selling) and drawn as a bubble at the closing price, green for buying and red for selling. Bubble size and colour intensity show how strong that flow is compared with the last 300 candles: the strongest 30% get full bubbles with their USD value, the rest stay as small dots. Unusually large bubbles flag aggressive buying or selling worth a closer look, often near breakouts, reversals or key levels.Seasonal Chart
Plots one line per calendar year showing the % change since the start of that year, with the current year highlighted against up to four previous years. Lining the years up on the same calendar shows whether the price tends to rise or fall in the same months, helping you spot recurring seasonal patterns. Treat it as context rather than a forecast: past seasonality does not guarantee future moves.Siacoin Markets
Siacoin Historical Data
About Siacoin (SC)
Siacoin, or SC, is the token used to buy file storage on Sia. Renters pay hosts to hold their files. Hosts can earn SC by giving space and meeting the terms of a storage deal. Sia's core product is a storage market, not a general smart-contract chain. Its guides explain how renters pick the amount of data, the term, and the price.
Sia's storage market
Sia links people who need file storage with hosts who offer disk space. The renting guide lets users choose how much data to store and for how long. Prices are set in SC. Hosts set rates for storage, contract fees, upload speed, and download use. This means each host can make a different offer. The guide says a usual contract term is three months, though the terms for a deal can vary.
How SC is spent
A renter uses SC to pay for a storage contract. The host also puts up collateral under Sia's contract rules. That stake can be lost if the host fails to keep the deal. The network records each contract on its chain. The token thus pays for a real service, rather than only for a vote or an app feature. The official guide sets out the link between the file, the host, and the payment.
Mining and total supply
Sia does not set a fixed maximum supply for SC. New coins come from proof-of-work mining, while the block reward falls over time. The official supply page says about 60.5 billion SC had been created by 6 June 2025. That is a dated total, not a live count of coins in the market. It also is not a fixed cap. The same page explains why new SC can still enter the system.
Sia v2 and node tools
Sia switched to v2 on 6 June 2025. This hard fork changed code and the rules that nodes must follow. The Foundation names renterd for renters, hostd for storage hosts, and walletd for wallet tasks. Later work added RHP4 and uploads that do not need a full contract. The roadmap also lists faster sync work. These changes affect how Sia stores data; SC remains the coin used for network payments.
Using Sia in 2026
Sia's roadmap says the Sia Storage app launched in March 2026. It lets people use the storage network without setting up their own node tools. The same page says browser users can stream files in Chrome, Brave, Firefox, and iOS Safari. Work on S3 support and desktop access is also listed on the roadmap. These are named steps in Sia's product plan, while SC still pays for storage contracts and related chain use.

Siacoin (SC) FAQ
What is Siacoin (SC)?
Siacoin is the token used to buy storage on Sia, a network that connects renters with independent storage hosts. Its official guide explains that users pay SC for uploaded files and hosts receive SC for storing other people’s data. Sia contracts set the storage amount, duration, and payment terms between those two sides.
What is SC used for?
SC pays for Sia storage contracts and related on-chain actions. A renter uses the token to arrange file storage, while a host may earn SC for the space and bandwidth it supplies. Hosts also post collateral under Sia’s contract model, creating a financial cost if they fail to meet the agreed storage terms.
How does the Sia storage network work?
Sia lets renters upload files to independent hosts and records their agreements through blockchain-enforced storage contracts. The official renting guide says contracts default to three months and form when files are uploaded through the described workflow. Hosts set their own prices, and they are compensated after meeting storage obligations rather than simply for announcing available disk space.
What is the current SC price?
For SC, the composite USD quote is $0.0008; it appears at the top of this page next to the coin name. The value aggregates supported exchange prices in USD; it is not the cost of renting storage on Sia. Sia’s renting documentation says host pricing is negotiated in SC, so token market price and a provider’s storage quote are two different figures.
What is Siacoin’s circulating supply?
The current circulating-supply field for SC is 49,751,295,000 SC. Sia’s official supply page says there is no fixed maximum supply because proof-of-work mining continues to create new coins. Its dated report recorded approximately 60.5 billion coins created by 6 June 2025, a historical figure that should not be substituted for the live market-data field.
What is SC’s all-time high?
SC’s highest recorded market price is $0.0929; the corresponding date is Jan 5, 2018. That is a historical market-price record, not the price charged by Sia hosts. Storage prices are set by providers in SC, while an all-time high describes the token’s trading value across the market. The two measures answer different questions about the same asset.
How has SC performed historically?
SC’s chart reflects the price series that FMchart can assemble from supported exchanges, while the Sia Foundation’s dated technical record covers changes such as the v2 hard fork on 6 June 2025. Sia’s 6 June 2025 v2 hard fork is a software event, not a row in a token-return table.
Does Siacoin have a maximum supply?
No fixed maximum supply is defined for SC in Sia’s official supply documentation. The page explains that coins continue to be created through proof-of-work mining, with a block reward that decreases as the chain advances. Sia links ongoing issuance to the need to compensate miners who maintain the network and process storage-contract activity.
What happened when Sia upgraded to v2?
Sia’s v2 hard fork activated on 6 June 2025 and changed consensus code, transaction formats, and the renter-host architecture. The Foundation warned that older software would no longer sync or form valid contracts after the transition. Its supported software includes `renterd` for renters, `hostd` for storage providers, and `walletd` for wallet functions.
Can people use Sia without running a node?
Yes. Sia’s roadmap says the Sia Storage app launched in March 2026 so users could access decentralized storage without setting up software themselves. The same roadmap describes browser-based access and streaming in Chrome, Brave, Firefox, and iOS Safari. These consumer-facing products simplify access while the underlying network still uses SC for storage-related blockchain activity.
