Any investor can succeed with the DCA strategy, whether in holding or in buying and selling. But the most success will be in case of long term holding, because by buying little by little means you can build wealth, but according to this strategy all investors are successful. If participating in the investment following the regular DCA procedure.
That's true, the DCA strategy has lived for so long in the world of investment and it can't fail unless the asset itself fails. It is summarily a means to average the income of the investor by averaging the striking price, but in the end, this can't amount to regret because, during the investment, some will be missed at a best favourable price, while many others will be saved at the best favourable price, which is reasonable in all ramifications.
Nonetheless, I do not support this strategy at all times, and anytime the market has fallen so well to the point that you feel sorry for it...lol, you can commit your money to it without thinking twice. You will only miss out on a great opportunity by DCAing at that time. However, if the price of the market has risen to some doubtful level, yes, that is the right time to DCA to make sure that you do not lose/miss much due to FUD.
