> Dollar cost averaging assumes you start with a pot of money and you choose to invest fractions of that initial pot over time. This is opposed to lump sum investing in which you'd invest the full pot of money at the start.
How is this not the same as:
> Dollar cost averaging works when you have a steady stream of income that you're contributing to your investments and you have a heavily diversified portfolio.
My "pot of money" is my salary over the course of my career and my "investing fractions of that pot over time" is twice weekly contributions.
Whether I start with the whole pot or not is of no consequence.
