As an investor it is never advisable to use to trading strategy expecially as a newbie that what to increase his Bitcoin portfolio for you may run at lost on the contrary and trading shouldn't be seen as Bitcoin accumulation strategy.
Also the buy the dip strategy because if an investor keep on waiting for Bitcoin to dip before accumulating such investor may wait till infinity if Bitcoin didn't dip and also waiting for dip is a way of missing more opportunities of accumulating Bitcoin when you can accumulate using the DCA strategy that allows you to accumulate Bitcoin irrespective of the price of Bitcoin, unless investors who has gotten to their maintance level may choose to practice buying the dip strategy because they don't need be buying frequently using the DCA strategy through their reserve fund they can as well buy the dip.
I think the recommendable strategy should be the lump sum strategy and the DCA strategy since it will help in increasing Bitcoin portfolio by buying in big size or accumulating little by little using the DCA strategy and hodl for long.
Of course it cannot be done because ultimately investing and trading are different so we cannot use the concept of trading for investing because it will not make sense and will not be forced like putting a square into a triangular space because ultimately these two things are different.
When we really want to invest then focus on investment strategies not referring to trading because it will never connect in the end.
Regardless of whether the strategy is done as long as we are sure of the method whether buy on the dip or DCA it will not be a problem but it should be understood that there will definitely be a priority scale in this case and in my opinion instead of waiting to buy on the dip which is unpredictable when the time will be more worth it running DCA in the end. But when you are really sure of the view of buying on the dip then do it because in the end there will be no coercion for anyone in the accumulation of bitcoin that they do because in the end in this case the sowing reaping system still runs in the sense that what we plant then that is what we will produce so in this case when you plant or invest bitcoin with a smaller nominal because of the wrong collection method then don't expect too much with the results of bitcoin commultaif will be a lot of course.
