What is Siacoin?
Answer sources checked
20 answers source-reviewed with Codex assistance. Reviewed . This review covers the answers, not exchange listings or the rest of the page.
How does Siacoin work?
Sia coordinates storage contracts and proofs on its own proof-of-work blockchain, using SC for payments and collateral-related operations. The v2 upgrade changes protocol and software requirements without introducing a replacement coin. Current wallets and storage software need to be compatible with the upgraded network.
Who created Siacoin?
David Vorick and Luke Champine authored the original Sia paper describing its decentralized storage design. Development now involves the Sia ecosystem rather than only those original authors. The paper's authorship should not be confused with a claim that either person controls every host or miner.

What is Siacoin used for?
SC is used to fund Sia storage contracts, transfer value and support the economics of hosting and mining. Renting storage or operating a host involves software and contract obligations beyond owning coins. Siafunds are a separate asset, so holding SC does not grant Siafund revenue rights.
Where can you buy Siacoin?
Check SC availability and native Sia deposit support on each platform's official site. Confirm that its wallet infrastructure supports the current Sia network rather than relying on old Sia-UI instructions. Trading availability does not establish that withdrawals, local eligibility or your intended payment method are supported.

How to buy Siacoin
Plan your purchaseHow much Siacoin?
How can you buy Siacoin safely?
Verify native SC, the recipient's Sia address and the platform's current withdrawal support before buying. Use official v2-compatible wallet guidance and compare the final amount received. A message requesting a token swap or recovery seed because of the Sia upgrade needs independent verification through official channels.
Can you buy a fraction of Siacoin?
You can own a fraction of SC rather than a whole coin. Platform order minimums and withdrawal charges may limit which purchases are practical. When sending that balance, Sia's wallet displays the amount and estimated network fee separately, so retain enough spendable SC for the transaction.
How much does it cost to buy Siacoin?
Buying SC may involve a spread, trading commission, payment-provider charges and a withdrawal fee. A native Sia transaction has its own SC network fee, shown during wallet review. Storage-contract costs and host collateral are separate from the cost of a simple coin purchase.
How much is one Siacoin worth?
Use this site's timestamped dynamic reference panel for the current SC reference price and compare it with a platform's executable quote. Storage contracts have their own costs and collateral requirements. A market price for SC alone does not tell you the complete cost of renting or hosting storage.
Is Siacoin a good investment?
SC has price, custody and adoption risks, while Sia's storage model also depends on functioning hosts, miners and compatible software. Host contracts and locked collateral introduce obligations that passive holders do not necessarily face. Neither storage demand nor an upgrade guarantees returns. This is not financial advice.
Compare two order previews
Use SC credited after buying fees and spread. Extra USD charges must exclude fees already included in the total. Enter 0 only when confirmed.

Siacoin wallets & storage
How do you get a Siacoin wallet?
Use current Sia wallet software such as walletd, following official setup and recovery instructions. The v2 upgrade changed wallet tooling, so do not assume old and new seed formats are interchangeable. Back up the appropriate recovery material before receiving SC and verify the generated native Sia address.
How can you store Siacoin securely?
Keep your Sia recovery seed private and offline, and use the official wallet workflow when signing transactions. Confirm that backup and recovery instructions match the wallet version you actually use. Legacy Sia-UI material may not describe current walletd behavior, and a storage-host login is not a wallet backup.
Sending & cashing out Siacoin
Match your networks
For SC, copy the exact network names shown in your apps. This compares your entries, not a verified list of supported networks.

Copy the exact network name shown for this asset in each app. No supported-network catalogue is assumed here.
How do you send Siacoin to another wallet?
In walletd, choose the sending wallet, enter a native Siacoin address and amount, then review the estimated fee before signing and broadcasting. Sia warns that transfers to mistyped or other-cryptocurrency addresses cannot be retrieved. Verify the address independently and consider a small test transfer first.

How long does a Siacoin transfer take?
A Siacoin transfer must be broadcast and included in a Sia block before confirmation can be assessed. walletd can initially show an unknown or sending state; that is not proof of failure or final settlement. Exchanges may require additional confirmations and processing, so no universal completion time applies.
Source 1
How much does it cost to send Siacoin?
Native Sia transaction fees are paid in SC, and walletd provides an estimate before signing. The applicable cost depends on the transaction and network conditions rather than a fixed dollar charge. Storage contracts can involve additional payments or collateral that are not ordinary transfer fees.
Can you cash out Siacoin for real money?
To cash out SC, verify that your platform currently accepts native Sia deposits and supports the upgraded network. Send to its exact deposit address and wait for its required confirmations before trading. Fiat withdrawal availability, charges and processing are platform-specific and separate from blockchain confirmation.
Is Siacoin traceable?
Sia's blockchain records coin transfers and storage-contract activity, so SC should not be treated as an anonymous-payment coin. Public addresses can become linked to identities through external records. Encryption of stored files addresses file confidentiality, not automatic concealment of the associated payment or contract history.
Supply, mining & staking
What is the maximum supply of Siacoin?
Siacoin does not have a fixed maximum supply like Bitcoin: its documented mining schedule continues issuing SC. Supply growth is therefore distinct from the amount currently circulating or available on exchanges. Siafunds have different economics and must not be added to SC as though they were the same token.
Can you mine Siacoin?
SC is mined through Sia's proof-of-work blockchain. Mining secures transactions, whereas running a storage host supplies capacity under storage contracts; these are different activities. Hardware, electricity, network difficulty and operational costs affect mining results, so participation does not guarantee a profitable or reliable payout.
Can you stake Siacoin?
SC does not offer native proof-of-stake delegation because Sia uses proof-of-work. Hosts can commit collateral to storage contracts, but that is a service obligation, not consensus staking. Third-party SC yield programs or Siafund holdings have separate terms and should not be described as native SC staking.
