Why this exists

Decisions over hype

Markets move fast. Clear numbers—PnL, breakeven, risk, targets—help you act on a plan instead of emotions.

Fast & privacy-friendly

No sign-in for the tools. Calculations happen in your browser and we fetch prices from public APIs.

Beginner to advanced

From simple converters to position sizing and DCA simulations, everything is explained right where you need it.

How it works

Live pricing & charts

We query CoinGecko for spot prices and historical candles. Indicators like RSI and moving averages are computed locally in the browser for speed.

Supported coins mirror our main list (BTC, ETH, SOL, etc.).
Daily intervals for history keep pages fast and light.
No API keys required for visitors.

What the AI does

The AI chat on the AI page turns live metrics into quick answers for PnL, breakeven, position size, converter and targets—plus signals like RSI and 30D volatility.

It’s a helper, not financial advice.
Outputs are deterministic math over current market data.
No personal portfolio data is stored by us.

How we keep it free

Ads

We use standard display ads in clearly marked areas. When AdSense isn’t configured, we hide placeholders.

Affiliate links

Some exchange buttons are affiliate links, always labeled as “Sponsored”. You never pay extra.

No paywalls

Core tools, AI helper, and long-form guides are free to use. If this changes, we’ll say it clearly.

We believe in transparent monetization: clear labels, no dark patterns, and no selling of personal data.

Data sources & limits

Prices & history: CoinGecko public API.
Indicators: Calculated client-side (RSI, MA20/50/200, volatility).
Latency: Spot prices can be slightly delayed vs. exchanges.

Accuracy: Calculators are tested with edge cases (fees, decimals, large sizes).
Outages: If an API rate-limits or fails, tools still work with manual inputs.
Advice: Educational only—always do your own research.

Roadmap

Now — Improve AI chat prompts & visual polish, add more quick examples, and per-tool mini tutorials.
Soon — Optional CSV export for DCA simulations & PnL breakdowns.
Later — Alert presets (email/push) for targets and stops. Privacy-first by default.
