I don't really know if the question is really clear for you guys but I can explain with an example so that it's clear for everyone.
Let's imagine you got 30$ profit today as passive income from your business. Would you invest it today itself or would you rather wait till the end of the month and invest the accumulated profits that you made that month?
Note : I know that you're not supposed to invest full amount of money. Forget all those variables as of now.
Update : Thank you so much for all your answers.
Anyway, this particular cliche ‘time in the market beats timing the market’ solved everything for me.
This is such a great sub and I'd definitely contribute what I know.
