Dollar Cost Averaging (DCA)

Dollar cost averaging (DCA) is when someone invests fixed amounts (such as $20) at regular intervals (every week). This is a strategy used by investors that wish to reduce the influence of volatility over their investment.
As a result, the investor would be purchasing less of an asset while the prices are high and more of an asset while the prices are low.

The name “dollar cost averaging” is because the strategy opens the potential for reducing the average cost of the total amount of assets purchased. 


Let’s look at an example of how dollar cost averaging may work:

On the first of January, Alice and Bob decide they wish to invest in Bitcoin. Bob and Alice have different investment strategies

Bob wishes to purchase $500 of BTC each week until he accumulates one entire bitcoin.

Bob managed to accumulate one BTC for a total price of $9500 over time by investing $500 each week regardless of the price volatility. 


Alice, on the other hand, believes it’s better to purchase one whole bitcoin at once.
