Another good thing is that it lessens the impact of volatility as the total investment sum is spread over multiple purchases of the security. This strategy can be very effective if employed during bearish market.
DCA doesn't lessen volatility impact completely. It can be useful for wide spread of multiple purchases but at the end it doesn't guarantee any short term security because volatility is a two way mechanism, it's either pumping or dumping and sometimes it moves faster than imagined.
Lastly, the strategy can be applied in any crypto investment, bonds, stocks or any commodities. It's a fine choice! However, you can always stick to what is best for you as an individual.
Undoubtedly DCA is the best strategy for digital assets and investments but it also requires discipline because no strategy is 100% efficient. With every strategy lies hidden strategies. Knowing how to use DCA to one's advantage especially when the market moves in opposite direction is also a plus.
