Comet (CMT)

Comet ranks #447 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5488: 5041 of the 5487 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.

CoinSpectrum Grade (Source)

Grade pending. Comet's launch — how much went to insiders, whether it was sold to investors — is still being researched. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

Network privacy (Origin hidden by default)✗Comet wallet source (last commit Jul 2016): no Dandelion relay in the node; Tor is only an optional proxy setting (-tor/-onion) the user must configure.
Hidden amounts (Amounts confidential)✗Comet wallet source (last commit Jul 2016): Bitcoin-style transparent outputs; no confidential amounts.

Smart contracts (Scripting for spending conditions)1Comet wallet source (last commit Jul 2016): Bitcoin-style Script (signatures, hashes, CHECKMULTISIG) limited to spending conditions; no contract platform.
Multisig and time locks (Without a third party)✗Comet wallet source (last commit Jul 2016): CHECKMULTISIG is present, but the script interpreter has no OP_CHECKLOCKTIMEVERIFY or OP_CHECKSEQUENCEVERIFY (the code base predates BIP65/BIP112), so no output can be time-locked.
Atomic swaps (With other chains)✗Comet wallet source (last commit Jul 2016): without a lock-time opcode Script cannot express the refund branch of an HTLC, and no adaptor-signature swap exists for the coin.

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.

How CoinSpectrum ranks Comet

Comet is #447 among cryptocurrencies and #5488 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 5041 places between Comet'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).
