Seeing how things sometimes go up and other times go down, I think the best thing is to buy gold or dollars, put them under a pillow, and call it a day—or make a little stash and bury it somewhere safe in the house! Because, really, with all this technology, nothing is safe. If the stock market doesn't crash, it goes up and you bet the opposite way, or a hacker gets in, and that's it, goodbye. So nothing is safe. Getting rich here is super difficult.
