Yes, DCA is one of the best method and too be honest as you mentioned we should never be carried away with the current trends and popular choice because when market is good people will ask you to invest and even if it dumps by 5% they will be the first one asking you to withdraw and if we go by everyone's suggestion we will lose everything. It's better to have a calculated approach and I have tested this personally and so far it has been one of the best year of my crypto journey.
i also feel that dca is the best method for investing in bitcoin, especially for beginners who are just starting to invest in bitcoin, the dca method helps them to invest long term and mitigate the risks of the unstable bitcoin market. this method also makes it easier for investors to invest regularly and without the hassle of market analysis to determine their position, so that beginners can focus on investing without having to get tired of learning to trade like a trader.
