The biggest thing is you don't have to contribute actual money. Instead of watching the website's intrusive, tracker-ridden ads, you're receiving custom ones from Brave tailored to you based on a local machine learning profile. You're watching ads on your own, separate from the ad networks used by the websites, and so you get a virtual token that can be sent to creators you like. They can convert it to actual cash (you can too if you want).

Creating a virtual currency sounds like a abstraction layer that has no real benefit to me.

What do you mean by native pay services?

Services that work with real money and not over a virtual currency.

The whole point is no money is invoked for the browser user unless they want to go to the frog me of withdrawing the bat they earned. Instead they can just assign it to someone they support

That's what's superior. Real money services require someone to pay real money.

This system could be done without the coin but I bet it would be more difficult to arrange transfer to each browser user.

Like Money services crypto currency services also cost money.
