Sounds interesting, but my threshold is probably too high, and I would skip most of them. When was the last time you enjoyed watching an ad? I can't remember, but it's rarely the case. If you combine this with the chance that you are the target of the ads, it's pretty low.
I've invested in BAT during their ICO and today I feel like I'm hustling my investment a little bit. :-)
I mostly use Brave on my phone because it makes the browsing experience faster and removes most ads by default. I won't change to another browser on the iPhone anytime soon. Having said this, I haven't used the payments feature outside of web3 (Ethereum DApps).
I don't watch ads with any interest or attention in general, but I often have Youtube playing some live concert on the background while I work and ads cut midway forcing me to change tabs so I can skip them. The idea that instead of breaking my concentration to stop an add playing I can simply let them and that _that_ could be a little money generating activity seems appealing.
