S- DCA and traditional DCA have their own benefits and properties depending on the time, but if I can share my views, then I am supporting both S-DCA as well as DCA, and it depends on users which strategy is best for them. In DCA, you stick to a fixed amount and put it in when the price is low, but in smart DCA, you can change your amount and use algorithms and data analysis to fix your amount according to the market and will invest small when the price is high and invest more when the price is low.
