Fractal Bitcoin (FB)

Fractal Bitcoin ranks #90 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #539: 449 of the 538 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 544 non-native assets CoinSpectrum lists above it by market cap, about 59% are tokens, 33% are claims on other assets and 8% are memecoins.

Developer share (after launch)10No developer share: every new coin goes to the miners or validators who produce blocks. The 105M pre-allocation (50% of the cap) was minted at launch (Sep 2024) and is counted as premine. Block rewards (25 FB, halving every 2.1M blocks) go to merged and permissionless miners. Since FIP-101 (2026), a third of rewards goes to indexers and the FB stakers who back them. These are permissionless participants, not a developer, foundation or treasury, so this is not counted, although only the official Fractal indexer ran in the first test stage. source

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.

The work behind it

392 EH/s is recorded against Fractal Bitcoin, but it is merge-mined in part and the split between its own blocks and a parent's is not published — so its own share reads as unknown.

What a regulator has said

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.

How CoinSpectrum ranks Fractal Bitcoin

Fractal Bitcoin is #90 among cryptocurrencies and #539 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 449 places between Fractal Bitcoin'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).
