About CoinView · ABOUT
Who built this, and why.
LUNA in May 2022 was a shared scar for the crypto crowd. In hindsight, on-chain data (exchange UST balances, Anchor deposit changes), derivatives indicators (funding turning negative 6 days early), SOPR — half a dozen core indicators were shouting from the data two weeks before the collapse, and most retail traders couldn't read what they were shouting. CoinView exists for that problem: to write down how to read these indicators, plainly.
This site doesn't sell courses, doesn't run paid groups, doesn't host KOL shilling. All calculators pull live data from Binance, CoinGecko, and alternative.me public APIs. Every event case in every article is tied to a data point you can verify on Binance candles, Coinglass, or Glassnode.
We are in an Affiliate relationship with Binance. Our public referral code is BN16188. If you register with that code and trade, you pay the same standard fees — this money comes out of Binance's marketing budget, not from your trading fees, and never adds a cent to them. It is currently the only revenue source for this site, and no content goes soft because of it. Read the full disclosure.
