Crypto Dollar-Cost Averaging: A Regular-Investment Guide [2026]

1. What is DCA?

Dollar-cost averaging, DCA, invests a fixed amount at regular intervals regardless of market price. Buying ₩100,000 of Bitcoin each month is an example.

2. DCA versus lump-sum investing

The original guide illustrates buying $100 of Bitcoin monthly from January 2020, stating that by 2026 $7,200 invested would be worth approximately $25,000 or more. It acknowledges that investing the same total at once in January 2020 might have produced more, but emphasizes DCA's ability to support consistent investing with less psychological pressure.

3. A practical DCA framework

1. Choose an interval

• Weekly: More frequent price averaging, but more frequent account access.
• Monthly: A common choice that can be automated around payday.
• Daily: Highly distributed timing, with attention needed to fees.

2. Choose an amount

The source suggests 5–15% of monthly income and says not to invest living expenses or emergency savings.

3. Choose assets

• Bitcoin 70%: Described by the source as the safest cryptocurrency.
• Ethereum 20%: Described as the second-largest by market capitalization.
• Altcoins 10%: An optional allocation for growth potential.

4. Benefits and drawbacks

Benefits

• No need to time an entry or continually ask when to buy.

5. DCA and AI trading

The source presents DCA as suited to long-term investing and automated AI trading as suited to short- to medium-term trading. It suggests combining them to pursue both portfolio stability and returns.
