Lets see, if you bought one US dollars worth of bitcoin a month ago, and cashed out say, today, you would have gained- .000016, of a cent. I'd say, keep looking down, and pick up every penny you'd see laying on the street. You'd be money ahead- by a great deal.
You may want to reconsider your math, if you bought a Bitcoin at $32k a month ago and sold it today at $49k you would be up $17k minus taxes and fees, but it's like the casino, most people don't leave while they are still ahead. Buying a dollar worth of Bitcoin is like buying a dollar worth of cocaine, it ain't going to do much for you. The old-timers used to call a quarter 2 bits, that means you would get 8 bits for a dollar, or a bit would be worth 12,5 cents which is about what a Bitcoin should really be worth, but it's a pyramid scheme and they have enough people to believe in it to drive the price til the smart people pull out and move on to the next pyramid.
