BTC-Visualizer
BTC-Visualizer turns public Bitcoin data into a calm, readable dashboard that connects market action with network behavior, halvings, and supply scarcity. It is an educational open-source project, not a trading product.
Data story
Market, network, and protocol context instead of price alone.
Rendering model
Astro SSR with lightweight React islands only where charts benefit.
Open-source fit
Typed adapters, graceful fallbacks, and a sensible folder structure.
Project Context
The app combines register-less market and network history from Blockchain.com Charts with fee and retarget context from mempool.space. Responses are normalized on the server and cached briefly to reduce API churn.

Purpose
Education first
BTC is off its highs enough that cycle context and downside framing are still important for reading the market honestly.

Price History
Price is still the anchor metric, but the goal here is context rather than spectacle. The chart keeps controls minimal, marks halving windows subtly, and pairs the shape of the market with recruiter-friendly explanatory copy.

A weaker one-year trend makes timeframe selection more informative than a single headline price.
Cycle Context
Bitcoin’s supply issuance steps down roughly every four years. The timeline matters because it helps frame price history against supply policy instead of treating every cycle as a disconnected chart.
Current cycle progress

Scarcity
Supply is one of Bitcoin’s clearest product constraints. A scarcity view makes the protocol legible to non-crypto audiences and shows how issuance keeps slowing over time.

Issuance era
Late scarcity era
Block rewards are currently 3.125 BTC, with the next step-down projected in 744 days.
Only about 990,116 BTC remains to be mined, which keeps the scarcity narrative grounded in protocol math rather than marketing language.
Network Pulse
Market data tells you what people are paying. Network data helps explain what miners and users are doing. This section focuses on two readable signals: hashrate and fee pressure.
Low fee pressure suggests recent blockspace demand is relatively calm, which often contrasts nicely with market narratives driven by price alone.

This companion panel keeps the network section practical by surfacing the latest values people actually use.

Risk Lens
A simple drawdown chart says more about Bitcoin’s risk profile than another noisy indicator stack. It measures how far price has fallen from prior highs and keeps the downside story visible even in bullish periods.

Max historical drawdown

Deeper drawdowns make this chart especially useful because it turns volatility into a readable risk frame.
