Is it worth buying GPT-4?

Hello there, I'm considering investing in GPT-4, but I'm not entirely sure if it's a wise decision. Could you please elaborate on its potential value and if it's really worth buying? I've heard about its capabilities in language processing and AI advancements, but I'm still on the fence about committing to it. Could you provide some insights on its current market standing, future prospects, and any potential risks involved? Your expertise in the field of cryptocurrency and finance would be greatly appreciated in helping me make an informed decision.
