Siacoin ranks #92 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #542: 450 of the 541 assets ahead of it are not native coins but tokens or claims. A token is issued on a host blockchain rather than running its own; a claim stands for an asset already counted. Of the 548 non-native assets CoinSpectrum lists above it by market cap, about 59% are tokens, 33% are claims on other assets and 8% are memecoins.

Twenty criteria, weighted equally. The Cryptocurrency Standards have six sections: sound money qualities (six checks: scarcity, durability, fungibility, divisibility, portability, verifiability), privacy (five checks), scalability (four measures and three features), security (miner pay and seven checks), programmability (token issuance, smart contracts and five checks) and decentralisation (censorship resistance, no central team, who can mint, nodes, holders, premine, fundraising and developer share). Provisional: criteria marked — are not yet measured and are left out of the average. A rating of structure and market depth, not a price forecast or investment advice. How the grade is built · Highest-graded cryptocurrencies.
49,751,295,000 SC are in circulation, against no fixed cap — issuance has no defined end.
| Premine (allocated at launch) | 0% of today's supply |
|---|---|
| Sold by the issuer or insiders | 0% of today's supply |
| Developer share received since launch | 15.8% of today's supply |
| Developer share of new coins today | 50% |
| Fundraising | No sale and no investor round |
No premine at launch in 2015: every siacoin was issued per block. What the Sia Foundation has received since the 2021 fork — a one-off ~1.57B grant and 30,000 SC a block — is counted as developer share.
No siacoin was ever sold by its issuer. Nebulous's 2014 SiaNotes sale (~$120K, settled with the SEC in 2019) was of Siafunds, a separate asset that earns 3.9% of storage-contract value; it is not counted against the coin.
Since the 2021 hard fork (v1.5.4) the Sia Foundation received a one-off ~1.57B SC and then 30,000 SC a block, the same as the miners: about 10.2B of ~64.8B SC, ≈15.8% of supply (docs.sia.tech, Siacoin total supply; the per-block part alone ≈13.4%).
Docs give 60.5B created by 6 June 2025; the Oct 2026 figure adds 60,000 SC a block (miners plus Foundation) since.

Siacoin is secured by 4.04 PH/s of its own work. Hashrate does not compare across algorithms — a SHA-256 hash and a Scrypt hash cost different amounts to produce.
No SEC/CFTC determination — unclassified.
The regulator's position, reported as stated, not CoinSpectrum's. Assets nobody has ruled on are left unclassified rather than sorted by a guess.
Siacoin is #92 among cryptocurrencies and #542 in the market ranking, which lists wrapped coins, staked derivatives, stablecoins and tokens alongside them. CoinSpectrum counts an asset once, and counts only cryptocurrencies: assets with their own blockchain and their own consensus. A wrapped coin, a staked derivative or a stablecoin is a claim on something already counted; a token, memecoin or otherwise, runs on another chain's blocks. All of them are listed, each in its own section, and none is added to the total. The 450 places between Siacoin's two ranks are held by claims and tokens, not by other networks. The methodology sets out the rule and the counting rule argues for it.
The price above is the median of the exchanges the site reads live, checked every minute and cross-checked against a market snapshot (how market data is gathered). The grade is scored on published criteria, each with its source (the method). The site is independent, nothing on it is a paid placement, and its statements are signed (about CoinSpectrum, the manifesto).
