Our Mission
BitcoinMargin was built with a simple belief: access to quality financial tools and education should be free. The crypto space is filled with noise — shills, scams, and paywalled content that preys on beginners. We wanted to build something different.
Every tool on this site is free to use, requires no account, and works on any device. We don't collect personal data beyond what's needed for basic analytics. We don't sell courses. We don't run a fund. We build tools and write guides that we wish existed when we started.
What We Are
A free, independent educational platform
Builders of open-access trading tools and calculators
Transparent about our data sources and methodology
MiCA-compliant with clear risk disclosures
GDPR-compliant with minimal data collection
What We Are Not
Not a cryptocurrency exchange or broker
Not a financial advisor — we don't give investment advice
Not a custodian — we never hold your funds or keys
Not sponsored by any exchange (affiliate links are disclosed)
Not offering personalized financial recommendations
Data Sources & Accuracy
✓ CoinGecko Pro API
Live spot prices, market caps, and 24h volumes for the top ~250 assets are pulled from the CoinGecko Pro /coins/markets and /simple/price endpoints. Prices on dashboard widgets refresh every 60 seconds; deep-link coin pages refresh on each request and cache for 5 minutes server-side. If the API returns a 429 or 5xx response, the front-end falls back to the last cached value and displays the cache age.
✓ Binance Public API
Perpetual-futures funding rates, mark prices, and order-book depth come from Binance's public REST endpoints (/fapi/v1/premiumIndex, /fapi/v1/fundingRate). Funding-rate history is refreshed every 8 hours to align with Binance's funding interval; order-book snapshots used in slippage calculators refresh on user request. No API key is required for these public endpoints.
✓ Alternative.me Fear & Greed Index
The Crypto Fear & Greed Index value (0–100) and its component breakdown are pulled from the public alternative.me/fng API once per hour. Historical series for the chart covers the index since its February 2018 launch. If the endpoint is unreachable, the dashboard shows the previous day's value with a stale-data badge rather than a blank widget.
✓ Open Exchange Rates
Fiat conversion rates (USD, EUR, GBP, JPY, plus 160+ others) used in calculators are sourced from Open Exchange Rates' /latest.json endpoint, refreshed hourly against the USD base. Cross-rates are computed locally. If the feed is delayed by more than 6 hours, a warning is shown next to the converted figure and the timestamp of the last successful update is exposed.
✓ Metals-API & Oil Price Feeds
Spot prices for gold (XAU), silver (XAG), platinum, and palladium come from Metals-API at a 15-minute cadence during market hours. WTI and Brent crude oil prices are pulled from public commodity feeds with the same refresh window. These feeds power the BTC-vs-commodities comparison charts; weekend and holiday gaps are interpolated from the previous Friday close.
✓ Ethereum Gas & On-chain Data
Base fee, priority fee, and pending-block data come from Etherscan's gastracker API and a fallback public RPC node, polled every 15 seconds (one block-time post-Merge). Historical gas charts aggregate hourly medians since the August 2021 EIP-1559 activation. After the March 2024 Dencun upgrade we also surface L2 blob-fee data for Arbitrum, Optimism, and Base.
Note: All prices are indicative and may differ slightly from exchange prices due to API refresh intervals. Always verify on your exchange before placing trades.

Derivatives & Leveraged Products — Important Risk Warning
Derivatives are complex financial instruments that carry a high risk of rapid capital loss. Leveraged trading (futures, perpetual contracts, margin trading, options) can result in losses that exceed your initial investment. The majority of retail investor accounts lose money when trading derivatives.
You should carefully consider whether you understand how derivatives work and whether you can afford to take the high risk of losing your money. This content is for educational purposes only and does not constitute financial advice, investment advice, or a recommendation to trade derivatives.
In the European Union, crypto derivatives are classified as financial instruments under MiFID II. Only platforms with appropriate MiFID II authorization may offer these products to EU residents. Regulatory treatment varies by jurisdiction — verify the legal status of derivatives trading in your country before participating.
