Dollar-Cost Averaging Calculator
Dollar-cost averaging (DCA) is the strategy of investing a fixed amount at regular intervals, regardless of price. It's one of the most effective ways to build a Bitcoin position while reducing the emotional stress of trying to "time the market."
Why DCA Works
- ✓ Removes emotion: You buy consistently regardless of price swings
- ✓ Averages out volatility: Buy more when prices are low, less when high
- ✓ Builds discipline: Creates a sustainable investing habit
- ✓ No timing required: Nobody can predict short-term price movements
DCA Calculator Tool
dcabtc.com lets you model historical DCA performance. See exactly what your investment would be worth today if you'd started a weekly or monthly DCA strategy at any point in Bitcoin's history.
Example DCA Scenarios
| Strategy | Frequency | Annual Investment | Best For |
|---|---|---|---|
| Starter Stack | $50/week | $2,600/year | Building your first position |
| Fortnightly Saver | $100/fortnight | $2,600/year | Aligns with Aussie pay cycles |
| Monthly Builder | $500/month | $6,000/year | Serious accumulation |
| Full Cycle | $500/month × 4 years | $24,000 total | Complete halving cycle |
DCA vs Lump Sum
Historical data shows that lump-sum investing slightly outperforms DCA in rising markets—but most people don't have a lump sum ready to invest. DCA is psychologically easier, reduces regret, and is practical for those investing from regular income. For most Australians, DCA aligned with payday is the most sustainable approach.

Understanding your gains and losses is essential—not just for tracking performance, but for Australian tax compliance. The ATO requires you to calculate capital gains on every disposal.
Basic P/L Calculation
Note: This is a simplified calculator. For accurate tax calculations, use dedicated tax software or consult a professional.
🇦🇺 Australian CGT Reminder
In Australia, Bitcoin is treated as property. Every sale, trade, or use triggers a CGT event. If you hold for more than 12 months, you receive a 50% discount on capital gains (not losses).

Sats Converter
A "sat" (short for satoshi) is the smallest unit of Bitcoin: 1 BTC = 100,000,000 sats. As Bitcoin's price rises, thinking in sats becomes more practical than thinking in whole bitcoins.
Quick Reference
1 BTC
= 100,000,000 sats
0.01 BTC
= 1,000,000 sats
0.001 BTC
= 100,000 sats
0.0001 BTC
= 10,000 sats
Why "Stack Sats"?
The Bitcoin community embraces "stacking sats" as a philosophy: accumulate consistently, focus on satoshis rather than whole bitcoins, and think long-term. When BTC is $100,000, a $50 purchase gets you 50,000 sats—a meaningful amount when you think in these terms.
"The goal isn't to own 1 whole bitcoin. The goal is to own more sats than yesterday."

Transaction Fee Estimator
Bitcoin transaction fees vary based on network demand. Paying the right fee ensures your transaction confirms quickly without overpaying. This is especially important when the network is congested.
Mempool.space shows real-time fee estimates and mempool visualisation. It's the gold standard for fee estimation.
Understanding Priority Levels
🟢 Low Priority
Confirmation in ~1 hour to several hours
Best for: Non-urgent transfers, moving to cold storage
🟡 Medium Priority
Confirmation in ~30 mins to 1 hour
Best for: Regular transactions, most purchases
🔴 High Priority
Confirmation in next 1-2 blocks (~10-20 mins)
Best for: Time-sensitive payments, volatile conditions
💡 Pro Tips for Lower Fees
- • Weekends and nights (UTC): Often have lower fees due to reduced activity
- • Batch transactions: Consolidate multiple sends into one when possible
- • Use SegWit addresses: bc1... addresses are cheaper than legacy (1...)
- • Lightning Network: Near-instant, near-free for small amounts
Mining Profitability Calculator
Mining Bitcoin at home is rarely profitable for Australians due to high electricity costs. However, understanding mining economics helps you appreciate Bitcoin's security model and make informed decisions if you're considering mining hardware.
🇦🇺 Australian Mining Reality Check
Australian electricity averages $0.25-0.35/kWh—among the highest in the world. Most profitable mining operations pay $0.03-0.08/kWh. Unless you have access to extremely cheap power (solar with battery, off-grid, etc.), home mining in Australia is typically unprofitable.
Mining Calculators
Key Variables in Mining Profitability
- Hashrate: Your hardware's computational power (TH/s for ASICs)
- Power consumption: Watts used by your miner
- Electricity cost: Your $/kWh rate (check your bill)
- Pool fees: Typically 1-2.5%
- Bitcoin price: Revenue depends on BTC value
- Network difficulty: Adjusts every ~2 weeks
For most Australians, buying Bitcoin directly is more cost-effective than mining. If you're interested in supporting the network, consider running a full node instead—it's free and contributes to decentralisation.
