The only solution to fear or hesitancy in investing in Bitcoin is to take the investment to a strong position by doing regular DCA and building a decent holding. A backup fund is recommended to manage the investment successfully depending on the situation. A large holding should be held in short time intervals to reduce investment risk and buy in bulk in every downtrend.
Buying BTC on dips and saving large amounts of value to potentially invest into BTC on dips is not necessarily a good strategy for most regular people to really get involved in investing into bitcoin, yet if we are already presuming that our hypothetical person has a lot of hesitancies in regards to bitcoin then such a quasi-waiting strategy could work decently well for such hesitant person, even if it is not really generally a recommended strategy for most normies, and that kind of a waiting while investing very small DCAs strategy might work for that particular hesitant kind of a person just while they are still getting used to the idea of bitcoin and while they are continuing to DCA small amounts and to study bitcoin and get used to better attempting to understand what bitcoin is.
Elegantly speaking, when it comes to investing you won't find a crowd of perfectly knowledgeable people. They are usually eager to get more profit. I think the best solution is to do regular DCA without needing to be very knowledgeable about depositing bitcoins as this way a depositor can get a pretty decent stack by depositing long term without any stress. I have to agree with you that people necessarily keep their savings in anticipation of price dips that require them to burn more time to reach their desired point. It is possible for an aspirant to complete each cycle smoothly if DCA is performed consistently for long periods of time by tongue wetting.
People who are hesitating to accumulate Bitcoins can often suffer from FOMO because they are more worried about their capital whereas DCA is a simple strategy to naturally accumulate Bitcoins in addition to daily household needs. Individuals with FOMO may miss out on important value events at various times, causing them to regret later.
