Because those just starting out in investing generally only know that buying when prices drop is a good way to invest, this is similar to the Lump Sum strategy, which requires waiting for the price to drop before making a purchase, a common practice when first starting out. While there's nothing wrong with this strategy, it can potentially lead to panic when what they thought was a good price drop to buy actually happens when the price continues to fall. This panic stems from a lack of knowledge and understanding of the strategy being implemented, as well as a lack of knowledge about the potential and track record of the investment being implemented. It's crucial that when negative events occur, they know that they are temporary and will eventually recover. However, the fact remains that panic is always present because buying all at once when the price drops and when the price continues to fall will lead to regret and panic.
And DCA is indeed the best way to invest in Bitcoin or other volatile investments, because once we know and understand Bitcoin's track record and nature, choosing a DCA strategy is the right choice, and we can gain more knowledge over time. And what we do with the DCA strategy is to continuously make purchases regularly, weekly or monthly, in a fixed amount without paying attention to prices or market conditions and not hindering or changing the amount of purchases made consistently for long-term goals and in the long term will grow to be large and DCA is the safest, most comfortable and also worry-free strategy as long as it is for long-term goals.
