What is Dollar-Cost Averaging (DCA)?

Want a simple strategy for investing into cryptocurrencies like Bitcoin (BTC)? Then you need to know about dollar-cost averaging (DCA).

In this short post, I’ll overview what dollar-cost averaging is and how it can reduce your risk exposure, blood pressure, and get you investing ASAP.

Remember: I’m not a financial advisor and this isn’t investment advice. Check out my full disclaimer here.

What is Dollar-Cost Averaging (DCA)?

Dollar-cost averaging (DCA) is where you buy a defined dollar (or any other fiat currency) amount of an investment at a fixed interval, regardless of that investment’s price at that moment in time. In other words, you’re spreading your investment over a longer time period in regular and equal proportions instead of purchasing your investment in one lump-sum.


Instead of buying £13000 worth of Bitcoin in one lump-sum, you could purchase £250 worth of Bitcoin every week for an entire year at the market-rate (regardless of what that price is). You’ll invest the same amount by the end of the year by using this investment strategy, but your average Bitcoin purchase price will be different (hopefully better – more on this lower down).


Dollar-cost averaging isn’t sexy, but it has advantages:

  • Reduces your volatility in the long-term
    • You’re averaging out your purchase price.
  • Don’t have to worry about investing at all-time highs
    • You’re not trying to perfectly time the market.
  • It gets you started (with a plan) quickly and easily.


Before you begin with this strategy, you’ll need to define:

  • How much you’re looking to invest.
    • Consider lump sums available now, as well as any spare change you have each month.
  •  How many weeks you’d like to divide this between.
    • Higher risk exposure when you invest less frequently (e.g., once every month).
    • Lower risk exposure when you invest more frequently (e.g., once a week).
  •  Where will you buy Bitcoin?

Dollar-Cost Averaging vs Lump-Sum Investment

If you purchase during significant price corrections, purchasing in one giant lump sum can generate better long-term returns.

However, picking the perfect time to buy-in is difficult. What happens if you invest all your available funds into Bitcoin at £5000, but then it falls a further 20%? You’ve already invested all your funds, so what else can you do? You could try to scrape together some additional funds. But if you can’t, you would be stuck sitting on the bench – unable to take advantage of this lower price.

You don’t face this problem if you’re dollar-cost averaging. You’ll passively take advantage of such price movements without any stress. However, the returns from dollar-cost averaging into an investment can be lower than just buying in a one-off lump sum. But the risk you’re exposed to is lower too. This is because the impact of buying at any one moment in time is less.

What else should I do?
