KuCoin (KCS)

KuCoin ranks #26 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #73: 47 of the 72 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 63 non-native assets CoinSpectrum lists above it by market cap, about 59% are claims on other assets, 35% are tokens and 6% are memecoins.

Premine (allocated at launch)0100% of today's supply allocated at launch to founders, a company, a foundation or investors. All 200M KCS were issued by KuCoin in 2017 (100M ICO, 70M founders, 30M angel investors). That is more than the current total supply of 142.16M KCS after buyback-and-burn (CoinGecko, 2026-10-23), so the figure is 100. source
Fundraising0Sold by its issuer or insiders: 100% of supply was theirs to sell, 91.4% sold so far. Public ICO 13 Aug-1 Sep 2017 sold 100M KCS at 0.000055 BTC (~5,500 BTC, ~$20M) plus 30M KCS to angel investors before the ICO = 130M sold (matching Dropstab's 130M). 130M / 142,155,021 KCS (CoinGecko total, 2026-10-24) = 91.4%. 30M KCS went to angel investors before the ICO. Public ICO 13 August to 1 September 2017 sold 100M KCS at 0.000055 BTC each, about $20M (ByteTree, altFINS). One aggregator (Dropstab) reports $45M and 130M KCS, which conflicts. source
Developer share (after launch)10No developer share: every new coin goes to the miners or validators who produce blocks. No cut and no new issuance: KCS has a fixed, fully pre-issued supply reduced by buyback-and-burn; KCC validators are paid from fees, not minted rewards. source

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 the grade is built · Highest-graded cryptocurrencies.

All 200M KCS were issued by KuCoin in 2017 (100M ICO, 70M founders, 30M angel investors). That is more than the current total supply of 142.16M KCS after buyback-and-burn (CoinGecko, 2026-10-23), so the figure is 100.

30M KCS went to angel investors before the ICO. Public ICO 13 August to 1 September 2017 sold 100M KCS at 0.000055 BTC each, about $20M (ByteTree, altFINS). One aggregator (Dropstab) reports $45M and 130M KCS, which conflicts.

Public ICO 13 Aug-1 Sep 2017 sold 100M KCS at 0.000055 BTC (~5,500 BTC, ~$20M) plus 30M KCS to angel investors before the ICO = 130M sold (matching Dropstab's 130M). 130M / 142,155,021 KCS (CoinGecko total, 2026-10-24) = 91.4%.

No cut and no new issuance: KCS has a fixed, fully pre-issued supply reduced by buyback-and-burn; KCC validators are paid from fees, not minted rewards.

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 KuCoin

KuCoin is #26 among cryptocurrencies and #73 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 47 places between KuCoin'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).
