Features Guide
A plain-English tour of every tool on the site: what each one does, what its numbers mean, and when it's worth your time.

Try the CalculatorWhat is Dollar Cost Averaging (DCA)?
Dollar cost averaging means putting a fixed amount into an asset at regular intervals, whatever the price happens to be that day. You give up on trying to "time the market" and buy on a schedule instead, letting the average price work itself out over the long run.
The DCA Calculator
The core tool: what a given buying schedule would have been worth.
Investment Amount
How much goes in each period. Any number works, and $10 or $20 a week adds up faster than most people expect.
Frequency Options
Daily, weekly, bi-weekly (every 2 weeks), or monthly. Weekly is the most popular choice among people who buy by hand.
Date Range
Set a start and an end date. Past dates backtest against real prices; an end date in the future switches the tool over to projections.
Fee Percentage
Exchange fees usually land somewhere between 0.1% and 1.5%. Enter yours and every return on the page accounts for the drag.
Currency Support
Results display in USD, EUR, GBP, CAD, AUD, or JPY. The math always runs in USD and converts at display time.
Price Sources
Kraken or Coinbase historical data, your pick. Both are major exchanges with price history going back years.
Preset Scenarios
Not sure where to start? The preset buttons load a common scenario in one click:
- • $50/week for 5 years: the classic long-term schedule
- • $100/week for 3 years: shorter window, bigger contributions
- • "What if I bought the peak?": how DCA plays out when your first buy lands on a cycle top. Bitcoin's most recent all-time high was about $126,000 in October 2025, and the 2021 top near $69,000 is the older test case
Results & Analysis Tools
What the results screen shows you, line by line.
Portfolio Summary
Total invested, BTC accumulated, current value, and profit or loss in a single row. One toggle switches the balance between BTC and satoshis, the smallest Bitcoin unit.
Performance Chart
Portfolio value plotted across the whole period, stepping up with each purchase. A second tab shows the Bitcoin price over the same window.
Transaction History
Every purchase in a table: date, BTC price, amount invested, BTC bought, fees paid, and running totals.
CSV Export
Pull the whole transaction history down as a spreadsheet. Useful for tax records, your own tracking, or importing somewhere else.
Share Link
Generates a URL carrying your exact settings. Handy for showing someone a scenario, or just bookmarking your own.
Future Projections
Set an end date in the future and the tool projects forward from three editable annual rates: a loss, no change, and a gain (−20%, 0%, +20% by default). They are assumptions you can change, not forecasts.
Comparison Tools
How the same money would have fared somewhere else.
DCA vs Lump Sum
The same total, dropped in all at once on day one. Sometimes lump sum wins and sometimes DCA does; this tells you which it was for your period.
Asset Comparison
Bitcoin against the S&P 500 and gold over the same window, using real historical market data.
Savings Account Comparison
The same schedule parked in a high-yield savings account instead, with compound interest. Rates sit around 4-5% APY (annual percentage yield) and vary by bank, so the rate is fully adjustable.
Inflation-Adjusted Returns
Your returns in real terms, deflated by official CPI data from the Federal Reserve. What's left over is the gain in purchasing power.
Planning & Goal Tools
Set a target, then find out what it takes to get there.
Stacking Goal Tracker
Pick a target: 0.1 BTC, a whole coin, whatever you're after. The tracker shows how far along you are and how long the rest takes at your current pace.
Price Scenarios
Type in a price ($100k, $500k, $1M) and see what your stack would be worth there. It's arithmetic, not a forecast.
FIRE Calculator
Financial Independence, Retire Early. Enter your monthly expenses and it estimates the years to financial independence under the 4% rule, across three editable price scenarios — falling, flat, and rising — so the downside is never hidden.
Unit Bias Calculator
Bitcoin looks expensive until you count in satoshis. One BTC is 100 million sats, and a million sats is a far more reachable target than a whole coin.
Opportunity Cost Calculator
Enter a past date and an amount to see what that money would be worth today had you bought Bitcoin with it. Sometimes reassuring, sometimes not.
Share My Stack
Renders your DCA results as an image built for social media: total invested, current value, and return.
Fee & Cost Analysis
Where the money leaks out on its way in.
Exchange Fee Comparison
Fees side by side across Coinbase, Kraken, Binance, Cash App, Strike, Swan, and River, totaled for your specific buying pattern.
Cost Basis Tracker
Your average purchase price as it moves over time. That number is your break-even line, and it's what tax reporting is built on.
Live Dashboard Widgets
Network and market data, refreshed while you watch.
Halving Countdown
New supply gets cut in half roughly every 4 years, on a schedule every node enforces. The widget counts down to the next halving, expected around April 2028.
Live Blocks Feed
New blocks as they're mined, with height, time, transaction count, and size. Refreshes every 30 seconds.
Fear & Greed Index
A sentiment gauge running from 0 (Extreme Fear) to 100 (Extreme Greed). Context, not a trading signal: this site's own pages argue against trying to time the market.
Mempool Fees
What it costs right now to confirm a transaction fast, medium, or slow. Worth a glance before you withdraw from an exchange.
Hash Rate & Difficulty
The security side of the network: current hash rate, difficulty, and an estimate of the next adjustment. More hash rate means a more expensive chain to attack.
Supply Scarcity
Roughly 95% of the 21 million Bitcoin cap has already been mined. This tracks the exact percentage and how much supply is left.
Purchasing Power
What $100 has lost since 2015, set against what Bitcoin gained over the same stretch. Inflation on one line, appreciation on the other.
Lightning Network Stats
Lightning settles Bitcoin payments instantly and for close to nothing. This shows total nodes, channels, and network capacity.
Bitcoin Dominance
Bitcoin's share of the total cryptocurrency market cap. Rising dominance often means Bitcoin is outperforming altcoins.
Sat Converter
USD to satoshis at the current price. Type in a dollar amount, get the sat count.
Educational Resources
Longer reads, for when the numbers start raising questions.
Why Bitcoin?
Where Bitcoin's value comes from: verifiable scarcity, settlement nobody can reverse, portability without permission, and network effects. Plus a scorecard grading the popular claims.
Self-Custody Guide
Why holding your own keys matters, how hardware wallets work, and how to store Bitcoin without losing it.
Mining Guide
Proof-of-work, why halvings matter, and how the difficulty adjustment shapes mining economics.
Bitcoin Adoption Tracker
An interactive chart laying Bitcoin's adoption curve over early internet growth, so you can judge how early it still is.
