Re the cult thing: I read an eye-opening paragraph about it somewhere. Basically, yeah, if you've invested in it, you have to either fool everyone else to buying into your cult, so the price will rise and future-you can cash-out and make a profit, or more likely, you're trying to convince yourself that past-you wasn't an idiot that just burned a lot of money. Or worse, you've convinced yourself that the USD will turn to toilet paper, soon, soon!

It's applying the formula of the shit book "The Secret" ("if you want it really hard, the universe will give it to you") to getting rich...
