Yes, that is clear, all passive income generally needs an investment, or an initial investment, such as a youtube channel, if you do not have the relevant hardware to start a youtube channel and generate income, such as a PC, microphone, Peripherals and others you will not be able to obtain returns either, in addition to the investment of time required.Most passive means of income are actually what you invest your money in and so financial input needs to be there before you will be able to earn something from it.
