Cost basis is the weighted average price you paid for an asset across all your purchases. It determines your profit or loss when you sell and is essential for accurate tax reporting in most jurisdictions. DCA naturally smooths your cost basis by buying at many different prices over time.
Your cost basis is the weighted average price at which you acquired an asset. If you bought 1 BTC at $40,000 and another 1 BTC at $60,000, your cost basis is $50,000 per BTC.
Cost basis matters for two reasons:
1. Profit/loss calculation: if your cost basis is $50,000 and you sell at $70,000, your profit is $20,000 per coin. If you sell at $45,000, your loss is $5,000.
2. Tax reporting: in most countries, you owe capital gains tax on the difference between your selling price and cost basis. Accurate tracking is essential.
DCA naturally creates a smooth cost basis because you buy at many different prices. This is one of its key advantages — your cost basis reflects the average market price over your investment period rather than a single point in time.
Alpha Factory's portfolio tracker helps you monitor your cost basis across all holdings.
According to a CoinLedger survey (2024), only 28% of U.S. crypto investors accurately tracked their cost basis across all exchanges and wallets, while the remaining majority faced potential tax compliance issues from incomplete records.

Frequently Asked Questions
How do I calculate my cost basis if I bought at multiple prices?
Add up the total amount spent across all purchases and divide by the total number of tokens. For example, buying 0.5 BTC at $40,000 ($20,000 spent) and 0.5 BTC at $60,000 ($30,000 spent) gives a cost basis of $50,000 per BTC ($50,000 total / 1 BTC).
Does DCA affect my cost basis?
Yes — DCA naturally smooths your cost basis because you buy at many different prices. Your cost basis reflects the average market price over your investment period, rather than a single point in time. This typically results in a lower cost basis than a poorly timed lump sum.

Dollar-Cost Averaging (DCA)
Dollar-cost averaging (DCA) is an investment strategy where you invest a fixed amount at regular intervals — weekly, biweekly, or monthly — regardless of the current price. By spreading purchases over time, DCA reduces the impact of volatility on your overall cost basis and removes the pressure of trying to time the market.
Lump Sum Investing
Lump sum investing means deploying all available capital into an investment at once, rather than spreading purchases over time through DCA. Vanguard research shows it outperforms DCA approximately two-thirds of the time in traditional markets, but crypto's extreme volatility makes the timing risk substantially greater than with stocks or bonds.
Rebalancing
Portfolio rebalancing is the process of realigning the weightings of your crypto assets to maintain your original "target" risk level. It involves selling assets that have performed well and buying those that have underperformed.
Break-Even Point
The break-even point is the price at which an investment recovers its original cost basis, resulting in zero profit or loss. In crypto, understanding recovery math is critical: a 50% loss requires a 100% gain to break even, and a 90% loss requires a 900% gain.
