MonaCoin ranks #185 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1326: 1141 of the 1325 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 1549 non-native assets CoinSpectrum lists above it by market cap, about 74% are tokens, 20% are claims on other assets and 6% are memecoins.

A — 75 out of 100, provisional (from 19 of 20 criteria, 28 October 2026 build). With what is not yet measured anywhere from nothing to full marks, the score would be 71 to 76 (B to A).

| 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) | ✗ | Bitcoin-derived node relays its own transactions over clearnet by default; Tor (-proxy/-onion) needs user setup and there is no Dandelion. |

| Atomic swaps with other chains | ✓ | Script can express HTLCs (hash check plus CLTV/CSV refund). |
| An exchange built into the protocol | ✗ | No exchange in the protocol; Monaparty's DEX is a metaprotocol read by its own servers. |
| Cross-chain messaging the chain verifies itself | ✗ | No cross-chain feature in the protocol. |
| Non-fungible tokens | ✗ | No token type in the protocol; Monaparty assets are a metaprotocol. |

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.
65,729,675 of a maximum 105,120,000 MONA are in circulation — 62.5% of the total that will ever exist.
| 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 | 0% of today's supply |
| Developer share of new coins today | 0% |
| Fundraising | No sale and no investor round |
No genesis allocation or presale: the genesis block (31 Dec 2013) pays the standard 50 MONA, mining opened publicly on 1 Jan 2014 (block 100 at 00:04 UTC) and every later block follows GetBlockSubsidy (50 MONA halving every 1,051,200 blocks).
No sale of any kind is documented.
The whole coinbase goes to the miner; no developer or foundation share exists in the consensus code.
The May 2018 selfish-mining reorg attack on MONA (about ¥10M lost at an overseas exchange) predates the 2021-2026 window; no later attack was found. The queue's circulating figure (65.7M) disagrees with the protocol schedule and explorer rewards, which give ~98.2M issued. The single v0.20.4 release sits at the 24-month edge.

No source we can reach publishes a hashrate for MonaCoin.
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.
MonaCoin is #185 among cryptocurrencies and #1326 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 1141 places between MonaCoin'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).
