I feel this strategy will work best for me since I can continue to recycle my initial working capital over and over again which will allow me to scale quicker.The end goal is to have a large cash flowing portfolio which I'm prepared to work full-time at to ensure that I succeed.

People who hold large sums of cash outside the bank generally do so for the purpose of tax evasion.
