The mixing of strategies allows us to customize our money to our own circumstances and to attempt to maximize our preferences, yet our merely dividing up our funds into three parts does not guarantee that we are going to choose correctly, and also it could ensure that we have inferior performance as compared with if we had guessed (gambled) correctly. Sure, I personally prefer to at least consider all three possible ways of using a lump sum (buy right away, DCA and buy dips), but however I choose to divide does not mean that I am going to end up getting superior performance, even if I was able to tailor the methods to my preferences.
Practicing multiple strategies and using them in combination is an old habit of mine. I have adopted multiple strategies in my investment journey and have deposited Bitcoin. This has helped my portfolio grow rapidly and helped me manage my finances properly. I take a different approach to this. While everyone selects money for investment at the beginning of the month and does DCA, I select the remaining money from the remaining money at the end of the month after all expenses and invest it. My expenses are not the same every month. Some months I have more money left than I planned and some times I have less money left. It is very easy to plan investments from the remaining money. When I have more money left to invest, I plan to practice DCA along with mixed strategies with it and do it at a specific time. Otherwise, I stick to DCA. After preparing the required funds, I do not have to divide the prudent money, when the funds are not sufficient, I try to replenish the funds with half of the prudent income and invest the remaining half.
Basically, it may be good for us to practice different strategies depending on the situation and can help us increase our investment skills. However, we have to keep in mind that the strategies are not harmful to us in any way. You also have to be skilled in financial management.
