As beginners, I don’t think they need to look for other strategies besides doing DCA (dollar-cost averaging) unless they have a large amount of money they want to invest. However, even if they have a significant amount of money, I would advise them to start with a small amount and apply the DCA method.
I disagree with this sentence. Why would a novice investor exclude investment strategies from his list of research along with investment continuity? Are you trying to limit him to DCA strategy? Or are you trying to limit his knowledge? A novice should start investing with DCA and this strategy is the best strategy for him. But how would he compare how reasonable it was to advise him about DCA strategy? Or how would he choose the best strategy for him? Are you advising a novice investor to stick to someone else's advice?
Whether an investor has money or not, I would not discourage anyone from researching investment strategies, rather I would encourage them to learn them. Because if you are not aware of the strategies, how can you be a skilled investor? Or how can you make someone else differentiate between DCA and other investment strategies? I don't see anything wrong with exploring investment strategies to gain knowledge, but it's better for a beginner to not invest in a different strategy if they aren't already skilled at investing.
