Bitcoin is a bubble but that doesn’t mean that you can’t make money investing in it. All you need is someone else to be the “greater fool” to purchase it from you. Just don’t get stuck holding bitcoin when the bubble collapses.

Same thing could be said about sub-prime loans. Or really - anything. If you have this kind of "God-like knowledge", even gambling is a great idea.
