KUB Coin (KUB)
KUB Coin ranks #91 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #547: 456 of the 546 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 556 non-native assets CoinSpectrum lists above it by market cap, about 49% are tokens, 43% are claims on other assets, 8% are memecoins and 1% are NFT collections.

Grade pending. What KUB Coin pays its miners is not yet measured. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

| Premine (allocated at launch) | 0 | 100% of today's supply allocated at launch to founders, a company, a foundation or investors. Bitkub Blockchain Technology created the entire supply (1B KUB, reduced to a fixed 110M by burning 890M on 9 Aug 2021), and there is no further issuance; total supply is 110M. source |
| Fundraising (share sold) (Source) | – | Launch not yet researched |
| Developer share (after launch) | 10 | No developer share: every new coin goes to the miners or validators who produce blocks. No issuance: the supply is a fixed 110M (890M burned in Aug 2021) and no new KUB is minted, so there is nothing to cut. source |
| Decentralisation | 1.9 | average of 4 parts |
| Governance (Source) | 0 | An authority can halt the chain or freeze funds: Block production is limited to a small Bitkub-approved validator set (nine producers seen, one making over half the blocks), so the operator can halt or censor the chain. source |
| No central team (Source) | 0 | A central team directs it: Bitkub Blockchain Technology (Bitkub Group) runs Bitkub Chain; no public source repository for its node client was found. source |

| Protocol level privacy (Keys not tied to an identity · Whitepaper §10) | 10 | KYC in Bitkub NEXT gates that wallet and its dApp features; KUB can be sent to external addresses such as MetaMask, and the chain rules carry no identity check. |
| UTXO ledger (Separate outputs, change to a new address · Whitepaper §2, §9) | 0 | An account ledger: one running balance for each address, so the remainder stays at the sending address and its payments share one public history. |

| Smart contracts (General-purpose) | 2 | EVM-compatible chain supporting KAP and ERC standard contracts deployed with Ethereum tooling. |
| Multisig and time locks (Without a third party) | ✓ | Multisig and time-lock contracts on its EVM. |
| Atomic swaps (With other chains) | ✓ | Solidity HTLCs can be deployed on its EVM. |
| Native DEX (Trades the coin itself, not a claim) | ✓ | Traded as itself, not as a wrapped token or a claim: its own chain's DEXes (KUB, DefiLlama). |
| Cross-chain messaging (Verified by the chain itself) | ✗ | No protocol-level cross-chain messaging documented. |
| NFTs (Carried by the chain's rules) | ✓ | KAP-721 and ERC-721 contracts run by its EVM. |

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.

Bitkub Blockchain Technology created the entire supply (1B KUB, reduced to a fixed 110M by burning 890M on 9 Aug 2021), and there is no further issuance; total supply is 110M.
No token sale, investor round or airdrop amounts found in Bitkub's own materials; one aggregator mentions an initial airdrop to Bitkub Exchange customers. Not established.
No issuance: the supply is a fixed 110M (890M burned in Aug 2021) and no new KUB is minted, so there is nothing to cut.

How CoinSpectrum ranks KUB Coin
KUB Coin is #91 among cryptocurrencies and #547 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 456 places between KUB Coin'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).
