We 100% agree!
Which is why we make this clear right throughout the piece as we discuss revenue, expenses and profits. This quote forms part of our conclusion:
Our recommendation is that you should think hard about whether you’re willing to put in the many months of learning and experimentation required to (hopefully) turn a profit one day.
Maybe your skills are better suited to something else which is OK. Maybe your Internet connection goes down all the time and so it’ll just never work no matter how much you try. Maybe you don’t have enough Bitcoin to fund enough channels. Or maybe you don’t care about being profitable as you want to just learn. Whichever way you go, just know that it takes lots of work and know this going in.
