My posts only earn between $0.01 to $0.22. I noticed a post with $4+. This has kept me wondering if there may be or may have been a post with over $10.

Why do I ask such a question?  To produce a good quality post is not as easy as the way some people may think. Much goes into the production of such a post.  One needs to do research which is time consuming and may even have financial implication in the matter. 

Wi-Fi is also needed to be able to produce a post.  There are places where Wi-Fi may be cheap or free.  Such people are very lucky as their browsing is already paid for.  Those who use mobile data may find browsing to be very expensive.  When you are supposed to use about a dollar only to have returns of $0.03 is not economical and prudent at all. 

Time is also a factor to consider while producing a post.  A person does really invest his valuable time into the production of a post.  Time is money an should be invested into more income generating activities.

Now we were talking about the best earning post.  How much did your highest earning post earn? Which is your lowest earning? 

Contentment is another thing.  If you are contented with what you are earning then there is no problem. Yet one needs to better his work. 

What are the things which made your post earn greatly.? We need to know your secret.  I understand posts in cryptocurrency are best earners.  Is it a fact or a myth?  If it is a myth then what is the secret?
