I think the easiest way to earn online today is with cryptocurrencies, after getting to know cryptocurrencies I can earn even though it's small, I start earning cryptocurrencies from bounties and airdrops then I use it for trading and investing in new projects, although not always profit but I always take lessons for profit.
easy or not depends on the expertise that everyone has because everyone has different abilities. if someone has the ability to make interesting videos he can become a youtuber, of course income from youtube cannot be underestimated and is not inferior to income from crypto. not a few people who feel like a failure in cryptocurrencies and prefer other online income such as youtube or creating a blog.
