The main goal behind earning BAT in the first place was to use it, to support creators across platforms in a passive cost-efficient way by simply watching a few ads here and there.
Like with YouTube, watching content from a creator you like on Brave means, that the creator gets less to no revenue from Ads on YouTube, to counter this, a Brave user could opt in to tip said creator with his earnings.
Alternatively one could also just cash out… but that in terms never was the main goal as being a Browser that you as an individual could earn money.
A creator in terms with the power of many, could make a decent living for pouring so much time and effort in creating things.
But yes… it is also true that BAT honors your “Attention” by rewarding you with their Token. What you do with it in the end, is your own Business.
