Master the Dollar-Cost Averaging (DCA) strategy to hedge against volatility and learn how to set up automated "Recurring Buy" plans on OSL.

📖 What is Dollar-Cost Averaging (DCA)?

In this volatile market, have you ever felt anxious about "when to buy"?

Dollar-Cost Averaging (DCA) is a passive investment strategy designed to provide a "hands-free" solution for investors who want to steadily accumulate crypto assets over the long term without constantly staring at price charts.

Data doesn't lie: According to our latest survey, DCA has become the preferred strategy for crypto investors, with 59.13% of respondents using it as their primary method. While no strategy can guarantee 100% profitability, the unique "Set and Forget" nature of DCA makes it the best tool for long-term believers to navigate through bull and bear markets.

🔎 Core Principle: Why choose "Recurring Buy"?

The core of DCA lies in purchasing assets with a fixed amount of money at fixed intervals.

  • Smooth Out Costs: By making consistent small purchases, you buy more assets when prices are low and fewerassets when prices are high. This mechanism automatically lowers your average cost of holdings.

  • Counter Volatility: This strategy reduces the importance of "Timing the Market." You no longer need to gamble on hitting the market bottom. Instead, through long-term accumulation, you transform violent market fluctuations into a smooth asset growth curve.

How does DCA work?

DCA allows you to break up your capital without needing to commit a large lump sum upfront.

For example: Instead of going "All-in" with $10,000 today, you can set up an automatic plan: Buy $100 worth of Bitcoin every Friday. For most traders, trying to "catch the bottom" often backfires. By strictly following a DCA strategy, you leverage the power of time to build your crypto portfolio in a more passive, stress-free way.
