Flux ranks #106 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #695: 589 of the 694 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 697 non-native assets CoinSpectrum lists above it by market cap, about 61% are tokens, 30% are claims on other assets and 9% are memecoins.

| Premine (allocated at launch) | 10 | 0% of today's supply allocated at launch to founders, a company, a foundation or investors. ZelCash launched on 31 Jan 2018 as a GPU-mined coin with no ICO, IEO, pre-sale or premine; the 123M ZEL circulating at the March 2021 hard fork converted 1:1 to FLUX; current supply ~422.4M (CoinGecko). source |
| Fundraising | 10 | No sale of the coin source |
| Developer share (after launch) | 10 | Developer share: about 0.12% of today's supply received so far; 3.6% of each new block reward goes to them today. Since the PoUW v2 fork at block 2,020,001 (25 Oct 2025), 0.5 of the 14 FLUX per 30-second block goes to an ecosystem development fund held by the Flux Foundation (t3hPu1YDeGUCp8m7BQCnnNUmRMJBa5RadyA); the rest pays Cumulus, Nimbus and Stratus nodes, which now produce blocks. Before the fork the 37.5-FLUX reward was split between miners and FluxNodes with no foundation share. 1,044,807 blocks × 0.5 = 522k FLUX = 0.12% of 422.49M (explorer). 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. How the grade is built · Highest-graded cryptocurrencies.
422,796,034 of a maximum 440,000,000 FLUX are in circulation — 96.1% of the total that will ever exist.
| Premine (allocated at launch) | 0% of today's supply |
|---|---|
| Developer share received since launch | 0.12% of today's supply |
| Developer share of new coins today | 3.6% |
| Nodes or validators | 2,778 |
| Fundraising | No sale and no investor round |
ZelCash launched on 31 Jan 2018 as a GPU-mined coin with no ICO, IEO, pre-sale or premine; the 123M ZEL circulating at the March 2021 hard fork converted 1:1 to FLUX; current supply ~422.4M (CoinGecko).
No sale of the coin or investor round found. At the 2021 hard fork the Flux Foundation received 10M native FLUX plus 10M in parallel assets (locked, for DAO governance), and a share of each block reward goes to the Foundation.
Since the PoUW v2 fork at block 2,020,001 (25 Oct 2025), 0.5 of the 14 FLUX per 30-second block goes to an ecosystem development fund held by the Flux Foundation (t3hPu1YDeGUCp8m7BQCnnNUmRMJBa5RadyA); the rest pays Cumulus, Nimbus and Stratus nodes, which now produce blocks. Before the fork the 37.5-FLUX reward was split between miners and FluxNodes with no foundation share. 1,044,807 blocks × 0.5 = 522k FLUX = 0.12% of 422.49M (explorer).

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.
Flux is #106 among cryptocurrencies and #695 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 589 places between Flux'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).
