About BTCCO

My name is Jawad JD. I am a web developer, an SEO specialist with over 14 years of hands-on experience, and an active cryptocurrency trader. I have been building websites and ranking them on Google since before most people had heard the word "SEO."

Like many traders and crypto enthusiasts, I used to pay for tools that should be free. Profit calculators, DCA simulators, liquidation calculators, tax estimators — every platform wanted a subscription fee for calculations that are just math. Koinly charges $199/year. CryptoTaxCalculator charges $99+. Separate tools for every single calculation, each behind a paywall.

I got tired of it. So I built BTCCO.

BTCCO started as a personal project — a collection of the tools I use myself every day as a trader. Over time, it grew into something bigger: a comprehensive free toolkit for everyone who believes that basic financial calculators should not cost money. If you are making a trading decision, you should have access to accurate, fast, and free tools — full stop.

Every calculator on BTCCO undergoes rigorous mathematical verification against live exchange matching engines (Binance, Bybit, Kraken) and established quantitative finance models:

• Client-Side Execution: All numerical calculations run locally inside your browser sandbox. We never send your portfolio numbers, transaction size, or private data across the network.
• Multi-Tier Feed Redundancy: We ingest live cryptocurrency rates with triple-layered automated failover across CoinGecko, Binance, and Coinbase APIs to prevent stale quotes.
• Formula Transparency: Each of our 35 tools features an open, documented formula breakdown and step-by-step worked example directly below the tool so you can independently audit the math.
