4. Paid-to-Click PTC Websites: There are many PTC websites that will pay negligible amounts in Bitcoin for clicks and views theirs adds
This website allows users to choose between viewing ads that are 5 seconds, 10 seconds or 20 seconds, with different fees being awarded for each but you need to searching trust proof site with payment proof.
This is a waste of time. But the other ways that you had mentioned would earn you quiet a decent amount of BTC. Though people coming to Bitcoin or in cryptocurrency in general expecting free money is funny. Even though you don't use real cash to buy Bitcoin but in order to acquire it you need to pour your time and effort along with your skills which some of it you can learn online like editing. You can practice the way you construct your words in a forum like this one. It is a matter of dedication and hardwork.
I think paid to click ptc sites could be considered on the micro earnings category, as you earn few satoshis for completing small tasks like watching an ad for some seconds or downloading an app, taking a survey and so on.
Now these offers aren't so attractive, but they were many years ago, when bitcoin didn't exist and internet accessibility wasn't disponible for most people. Nowadays the problem is: there are many people on the internet for very few jobs opportunities.
