Your right buying on dips isn't the best strategy for beginners considering that fact that it doesn't support ongoing and consistent buying of bitcoin which i think I'd what most beginners should be most bothered about since they are just starting out, but that doesn't mean they also can't practice it, yeah it's could be quite difficult for someone who doesn't know much to identify a dip and most newbies could tend to want to be smart and end up waiting to long or trying to caught the lowest point of the price and might missout on the whole thing, but yeah if the strategy is understood I think anyone can use it especially as a backup strategy to accumulate more bitcoin in times of low prices.
DIP searches can be relatively difficult for new investors in BTC because of the paucity of considerations in their investment. Continual purchases can be supported if he considers the DCA method. The best strategy for them may be to keep BTC deposits as a long-term strategy regardless of monthly income. Before investing he should be prepared first about his capital growth strategy and to acquire the title of long term holder so that he does not have to take the risk of withdrawal of investment which is floating money. Adequate knowledge of DCA for new investors can make them smart investors.
although Bitcoin investment is not meant for everyone but it is an opportunity thatt has avail itself for every interested person be it poor or rich, although DCA strategy has help everyone so there shouldn't be excuse for anyone to be ababdone by the train,
DCA is a universal strategy for eliminating ability differences in investing that is applicable to people at all levels. Keeping in mind the ongoing consistent strategy and the habit of taking care of the BTC stack can make him a high quality holder in the future. You rightly say that the train waits for no one so I would say that the price that currently creates an opportunity to buy BTC will probably be a DIP for the foreseeable future. So regardless everyone should focus on BTC accumulation.
