Bitcoin's price only goes up as people buy it. "Making money" requires selling it. Selling it causes the price to go down. This is fundamentally the problem—unlike stocks, real estate, and other productive investments, one can only make money in Bitcoin by selling it for a higher price than it was purchased for.
There's a really cool ecosystem of decentralized systems starting to find real-world use cases on the other side of the bitcoin divide. Bitcoin is just the figurehead.
