To be honest with you, there's no such thing as an easy way to make money online. Disregard any site that promises huge earnings by simply doing a few task, as the majority of them are only out to scam unsuspecting individuals. Am talking from my personal experiences.
Writing on sites like this platform is as easy as earning online can get. But still, we both know it isn't easy earning here too as it involves both knowledge and self experiences to give a well thought and defined answer to any question. Plus it takes a lot of effort and determination to continue without relenting.
Some might recommend sites like paid to click (PTC). I don't know about others, but to me they are all a waste of time and effort. The best paying rate you can find on any of those ptc sites is maybe 0.001 cent per ads click. Do the calculations and see how long it will take to earn 1 cent, talk much of a dollar given their restricted total number of clicks per day. Small jobs or task sites are even better of than ptc sites. But they both have the same thing in common, low pay rate and minimal task availability.
Surveys on the other hand might seem like a better option, but there's the issue of qualification and certain regional restrictions to high paying surveys. I have no idea how their system evaluates people for taking surveys, but 60% of people always end up unqualified for certain high paying surveys when they apply. And besides, If you're not from the US, UK, AUS and sometimes Canada, there's high probability that you won't qualify for most survey sites.
My advice is that you stick to one system which you know you can work with. There are many freelance sites with various types of jobs available for online workers. Simply find one and put in the effort to make something out of it. No good thing comes easy, especially when it relates to making money.
