That's a common mistake among new investors. They don't have proper investment plans, they invest every money they have in Bitcoin hoping to get quick profits whereas Bitcoin investments are usually good for the long term because the price in the short-term is more unpredictable.
That is why it is said to invest only as much as you can afford to lose. Moreover Bitcoin investment is not that you will be able to earn profit from it just by investing and Bitcoin is not a get rich quick scheme. Bitcoin investment is likely to be successful in long term but short term investment can be profitable if you buy large amount of bitcoins at once during dip season and sell it during bull season.
This is why the DCA method can be one of the most effective ways to make us comfortable in investing without having to be burdened with the risks that exist because we are ready to lose because in the end knowing something like this from the start especially where we already know the method that we think is comfortable enough to do then this will make the situation better.
Keep in mind that you should also consider the reasons why the long term should be chosen over the short term because in the end when the DCA method you choose as your investment is clear this needs a continuous process and time so we cannot consider the short term as a consideration because it actually makes you indecisive so just focus on the long term by continuing to invest every week or month according to your readiness because in the end doing with the short term will only make you think of selling when the price is considered profitable and this will become a new problem where you cannot buy back because you already feel the price is not profitable to buy.
So that this does not happen, it will be more worth it if the long term is chosen from the start to make you feel comfortable without thinking about many things in the investment you are doing.
