FACTOR ranks #284 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #2625: 2341 of the 2624 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 2883 non-native assets CoinSpectrum lists above it by market cap, about 81% are tokens, 16% are claims on other assets and 3% are memecoins.

Twenty criteria, weighted equally. The Cryptocurrency Standards have five sections: sound money (six qualities: scarcity, durability, fungibility, portability, divisibility, verifiability), scalability (four measures and three features), security (miner pay and seven checks), decentralisation (censorship resistance, no central team, who can mint, nodes, holders, premine, fundraising and developer share) and privacy (five checks); programmability (token issuance, smart contracts and five checks) follows them. 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.

1,230,548 FACT are in circulation, against no fixed cap — issuance has no defined end.

Genesis 2022-04-20 has a zero reward; the README states there was no pre-sale, pre-allocation or pre-mining, and the reward function pays only the miner who factors the block's semiprime.
None documented; the README states no pre-sale or pre-launch distribution.
No sale; coins obtainable only by mining until exchange listing.
GetBlockSubsidy pays 0.111786 x 2^(factor bits/32) FACT to the miner only; no developer or treasury output.
Three payout addresses mined every sampled block in the last month, one with a majority (58.8%). The explorer node reports 27 peer connections, which is one node's peers rather than a network count, so nodes is null. No attack or halt reporting was found, but coverage of so small a chain is thin.

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.
FACTOR is #284 among cryptocurrencies and #2625 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 2341 places between FACTOR'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).
