extra earnings on line

There are many different ways to work online and make some earnings. Some ways need investments , some don't, depending on the line of work one is interested. Some are, for instance, placing their own websites on the internet and doing businesses. One can also do online writing and make some money, e.g. writing articles, short stories, reviews, commentaries, and so on. Those will be some extra income supplementing one's primary income.

You should work hard if you want to earn! If you take it as an "extra", the income will be maybe a little bit low, but if you take it serious, so you search for every sites that are legit and paying to maximize your earnings, then YES, you actually can make good money! Have a nice day!

If you treat it as a job, yes. If you treat it as an "extra side income" then probably not.

It gives you extra money, if you find the legit websites.
