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.
Yes, from both bounties and airdrops we can follow it for free, meaning without the need to spend capital, but of course there are some conditions,
although it can't always make a profit but at least we can also learn crypto,
nowadays making money online can be easily done by people as long as they are really serious
crypto is one of the other method to make money via online. there are many online job, no relate with crypto but still give you salary. maybe crypto give you more profit than the other, but, the problem is when people dont know about crypto. the experience know because they find crypto itself, learn it with many time. younger, must have guide to know what crypto is.
