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.

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.

| Cryptocurrency Standards (Source) | 6 | group average, 8 of 13 measured |
| Sound Money Qualities (6 checks) | 8 | 4 of 5 points, 1 not yet measured source |
| Scarcity: a fixed cap that holds, and a supply near 21 million | – | |
| Durability: five years or more with no halt, freeze or reversal | ✓ | 10 full years since its first recorded price, no halt, freeze or reversal in five years |
| Fungibility: every unit interchangeable, none the protocol can freeze or set apart | ✓ | no authority can freeze, blacklist or set apart a coin |
| Divisibility: the smallest unit worth a cent or less | ✓ | 8 decimal places, the smallest unit worth $5.1e-11 |
| Portability: fees of a cent or less and capacity for real demand | ✗ | about 37 transactions a second (3.1 on the throughput scale; 5 is the busiest networks' median demand) |
| Verifiability: open-source nodes and checking without a trusted server | ✓ | node software open source; light clients verify from headers or proofs |
| Privacy (5 checks) | 4 | 2 of 5 passed source |
| Whitepaper privacy: keys are not tied to an identity | ✓ | Comet's Bitcoin-derived node (cmtcoin/wallet) has no identity rule: anyone generates keys and receives and sends the coin. |
| UTXO ledger: a new key for each payment, no account linking every coin | ✓ | |
| Network-level privacy: the node hides where a transaction came from (Dandelion++, Tor or I2P, on 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 (confidential transactions, RingCT, shielded pools, Mimblewimble) | ✗ | Comet wallet source (last commit Jul 2016): Bitcoin-style transparent outputs; no confidential amounts. |
| Hidden sender and receiver (ring signatures or zero-knowledge proofs, one-time or stealth addresses) | ✗ | Comet wallet source (last commit Jul 2016): Bitcoin-style transparent addresses; no ring signatures, zero-knowledge spends or stealth addresses. |
| Scalability (fees, throughput, block time, block space, features) | 5.2 | average of 4 parts source |
| Fees ($0.001 or less 10, $1 or more 0) | – | not yet measured |
| Throughput (2,478 a second, the busiest network's peak day, 10; 119, the median of the ten busiest, 5) | 3.1 | about 36.9 simple transactions a second |
| Block time (10 minutes 10, less either side) | 7.5 | a block every 2 minutes |
| Block space per 10 minutes (32 MB or more 10) | 6.8 | 1 MB limit, 5 MB per 10 minutes |
| Features (3 checks) | 3.3 | 1 of 3 passed |
| Payments safe to accept within seconds | ✗ | Five-minute Litecoin-derived blocks with probabilistic confirmation. |
| Pruned nodes: a full node can validate and drop old history | ✗ | Comet wallet source (last commit Jul 2016): no -prune option; the node keeps the full block history. |
| Light clients verify payments from headers or proofs, without a trusted server | ✓ | Comet wallet source (last commit Jul 2016): proof-of-work chain whose node serves BIP37 bloom-filtered merkleblock proofs, so an SPV client can check headers and Merkle proofs. |
| Security (miner pay and 7 checks) | — | 2 of 3 points, 6 not yet measured source |
| Miners paid a day ($1,000 0, $10 million or more 10), 2 points | – | |
| Its own hashrate: at least half its algorithm's largest, not merge-mined | – | |
| Largest pool or validator under 50% | – | |
| Largest three under 75% | – | |
| More than one maintained client | ✗ | 0 |
| Node software is open source | ✓ | Single repository (cmtcoin/wallet) by an anonymous developer. |
| Real on-chain use: 1,000+ transactions a day | – | |
| No 51% attack or deep reorganisation in five years | ✓ | |
| Programmability (tokens, contracts, 5 checks) | 1.1 | 1 of 9 points source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts: scripting for spending conditions | 1 | Comet wallet source (last commit Jul 2016): Bitcoin-style Script (signatures, hashes, CHECKMULTISIG) limited to spending conditions; no contract platform. |
| Multisig and time locks | ✗ | 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. |
| An exchange built into the protocol | ✗ | Comet wallet source (last commit Jul 2016): no order book or market maker in the ledger rules. |
| Cross-chain messaging the chain verifies itself | ✗ | Comet wallet source (last commit Jul 2016): no cross-chain message or light-client verification in the protocol. |
| Non-fungible tokens | ✗ | Comet wallet source (last commit Jul 2016): no token or NFT type in the consensus rules. |
| Decentralisation | 7.5 | section average, 4 of 8 measured |
| Censorship resistant (Source) | 10 | No authority can halt the chain or freeze funds: No protocol key can freeze coins or halt the chain. 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.

No source we can reach publishes a hashrate for Comet.
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.
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).
