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.
Of course, income from Youtube will never be inferior to crypto if we can build a depth of content and constantly flow ideas associated with existing topics, sometimes I don't think this is a professional ability, this is a natural gift, many people are very professional but cannot make a perfect youtube channel while those who are just very ordinary and speak very close sentences are enough to become main trends and topics for many months. On the contrary, this is the strength of crypto for a start, there is no requirement for a content or recipe, working properly will have an income while youtube and blogs need to work exactly, the source of income here is from viewers, not a fixed paid budget
