I still think the two can perform equally depending on how you choose to put work into it. Leveraging well on the available technology the two can return well. But personally, I'll go with content creation. My reason being that(using YouTube as an example) if you get the required video to meet up the YouTube standard, even if you stop adding more content as along as the video is increasing, the income stream will still be active. But a better suggestion is combining the two, making content on crypto in this case you're getting the profit of the two.
Later given this a second thought i tend to understand that anyone could be better just like you have explained. The success for anyone nor the probability of one making you more successful than the other is based on our effort and resources we put on each other. Content creator may seem easy to start but don't forget that successful one makes use of quality tool in creating those contents. Like quality cameras, nice recreational l places and some other things. On the other hand, Crypto investment needs high funding for high return. There is nothing easy or anything that won't make us successful it depends on us to give it the right resources and time.
