Can you make money fast on Coinbase?

I've been hearing a lot about Coinbase and cryptocurrency recently, and I'm curious if it's really possible to make money fast on this platform. Is it just a flash in the pan or can you actually turn a profit quickly? I've seen some people claim they've doubled their investments in a short period of time, but I'm skeptical. Can you really make money fast on Coinbase, or is it more of a long-term investment strategy? I'd love to hear your expert opinion on this.
