Yes in terms of investment lump sum investment can be very useful for an investor if he has excess money supply but he has to choose the right time to do it like dips price trend. If you don't get suitable bearish then you can start depositing bitcoins with DCA method and if you get low price of bitcoins during deposits regularly then lump sum buy may be more useful for you to get more holding in less time.
The method of buying in large quantities at once requires the right time such as market conditions in a Bearish phase and a large amount of money. For me, this method is very boring because it takes a long time to wait for the market to correct. However, DCA offers a solution without causing problems, investors can invest at any time with any amount without having to be tied to market value. This method allows investors to accumulate Bitcoin at an average price over the long term, while also avoiding the stress of trying to predict volatile market price movements.
When it comes to buying Bitcoin using the lump sum strategy there's no right time those that use lump sum strategy don't wait for any dip or time if you are waiting for a dip or any right time then what you are doing at that time is not lump sum anymore, in lump sum strategy when you decide to buy using lump sum strategy you don't care if there's a dip or good market condition you just accumulate and hold and that is what lump sum is all about.
All strategy is good, it all depends on a person I know of a big business man he said he does not have time to be accumulate Bitcoin week or monthly because he has other business his run and may even forget to accumulate some weeks or month if he uses DCA strategy because of his busy schedules that lump sum strategy is better for him, So everyone should do what works for him or her.
And you saying lump sum strategy is boring is not correct anyone who has other business he or she is running won't see it as being boring don't generalize something base on your own perspective.
