Well, yeah: If it's bullshit, you invest and then make sure you spread the word so there are enough people under you in the pyramid to keep you solvent.
Haha, very funny. I thought its obvious you don't invest if its bullshit. Also the whole point of using disposable income is that even if it tanks you stay "solvent". And no, look through my decade long comment history and you'll see not a single instance of me promoting crypto to anyone. In fact I actively discourage people who are looking for real investment from it.
