Universal Currency (UNIT)
Universal Currency ranks #395 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5451: 5056 of the 5450 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. No market cap or no daily volume is reported for Universal Currency by any source the site reads. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

| Fundraising (share sold) (Source) | 10 | No sale of the coin source |
| Developer share (after launch) | 10 | No developer share: every new coin goes to the miners or validators who produce blocks. PoW and PoS rewards go entirely to block producers; no developer share in the code. source |
| Decentralisation | 9.3 | average of 3 parts |
| Governance (Source) | 10 | No authority can halt the chain or freeze funds: No protocol-level party can freeze, blacklist or claw back coins. source |

| Features (3 checks) | 3.3 | 1 of 3 passed |
| Fast payments (Safe to accept within seconds · Whitepaper abstract, §1, §2 and §11) | ✓ | The PPCoin-style node has transaction replacement disabled and relays the first-seen spend; one-minute blocks alone would not qualify. |
| Pruned nodes (Old history dropped, every rule checked · Whitepaper §7) | ✗ | UnitCoin 1.0.2.1 (Nov 2017, PPCoin-era code) has no pruning mode; nodes keep every block. |
| Light clients (Payments verified from headers · Whitepaper §8) | ✗ | UnitCoin (PoW/PoS) (pre-BIP37 code) serves no Merkle proofs or block filters, so light wallets trust servers. |
| Privacy | 7 | 7 of 10: whitepaper privacy 7 of 7, extra features 0 of 3, 1 not yet researched source |
| Protocol level privacy (Keys not tied to an identity · Whitepaper §10) | 10 | Universal Currency's Bitcoin-derived node (unitcurrency/unitcurrency) has no identity rule: anyone generates keys and receives and sends the coin. |
| UTXO ledger (Separate outputs, change to a new address · Whitepaper §2, §9) | 10 | Coins are separate unspent outputs: a payment spends whole outputs and sends the change to a new address, so the coins in one wallet need not share a history. |
| HD addresses (A new address for each payment, unlinked · Whitepaper §10) | – | |
| Hidden amounts (Amounts confidential) | 0 | Transparent Bitcoin-style amounts; no confidential transactions. |
| Hidden parties (Sender and receiver hidden) | 0 | Transparent addresses and inputs; no ring signatures or stealth addresses. |
| Network privacy (Origin hidden by default) | 0 | UnitCoin 1.0.2.1 (Nov 2017, PPCoin-era code): no Dandelion; Tor is only used if the operator runs and configures it. |
| Programmability | 1.1 | 1 of 9 points source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts (Scripting for spending conditions) | 1 | Universal Currency runs Bitcoin-style Script limited to spending conditions (signatures, hash locks, multisig); no contract VM or token introspection. |
| Multisig and time locks (Without a third party) | ✗ | OP_CHECKMULTISIG is present, but the PPCoin-era src/script.h has no OP_CHECKLOCKTIMEVERIFY or OP_CHECKSEQUENCEVERIFY (0xb1 is still OP_NOP2), so Script cannot enforce a time lock. |
| Atomic swaps (With other chains) | ✗ | Without a consensus-enforced CLTV or CSV, Universal Currency Script cannot express the time-locked refund of an HTLC; only pre-signed nLockTime refunds, which pre-SegWit malleability makes unsafe. |
| Native DEX (Trades the coin itself, not a claim) | ✗ | No DEX found trading the coin itself: none on its own chain (DefiLlama), and not on THORChain, Maya, Chainflip, Komodo DeFi, BasicSwap, Bisq or Haveno (checked 2026-11-04). |
| Cross-chain messaging (Verified by the chain itself) | ✗ | Universal Currency nodes verify no other chain; no protocol-level cross-chain messaging. |
| NFTs (Carried by the chain's rules) | ✗ | No token or NFT type in the Universal Currency consensus rules. |
| Demand | 0.5 | average of 2 measures |
| Exchanges (10 or more: 10) | 0 | no exchange the site reads trades it |
| Daily volume ($10K 0, $1B or more 10) | – | no volume reported |
| Turnover (volume ÷ market cap, 5% a day: 10) | – | not measured |
| Order-book depth (±2% of the price ÷ market cap, 1%: 10) | – | not measured |
| Market cap ($1M 0, $10B or more 10) | – | not measured |
| Paper trading (futures, options and margin ÷ market cap, 0%: 10, 100%: 0) | – | not measured |

| Record | 6.7 | average of 3 criteria |

Ten sections, weighted equally, each 0 to 10: consensus (the two ladders), supply (the supply scale and a fixed cap that holds), distribution (premine, fundraising, developer share, holders), decentralisation (governance, no central team, who can mint, nodes), security, scalability, privacy, programmability (what the scripting layer can do beyond the whitepaper's payment system), demand, and record (age, development, conduct). They are built from the criteria in the second table: privacy, scalability, security and decentralisation are the Cryptocurrency Standards among them, as follows: privacy (the whitepaper's three checks a base of 7 of 10, three extra features up to 3 more), scalability (four measures and three features), security (pool diversity, network activity, hashrate, clients and two checks) and decentralisation (governance, no central team, who can mint, nodes, holders, premine, fundraising and developer share); programmability (token issuance, smart contracts and five checks) follows them, and supply and demand are two: the supply, scored against 21 million, and demand, the average of seven measures of the market and the wallets. Provisional: parts 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
No source we can reach publishes a hashrate for Universal Currency.
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 Universal Currency
Universal Currency is #395 among cryptocurrencies and #5451 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 5056 places between Universal Currency'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).
