Fundamental Question

Why Brave need BAT? Why the team don’t use other coin as reward and decided to use BAT in the ecosystem. I know there should be some reason. Could someone please explain to me. Thanksssss.

idk but could be cause of the other coin exchange rate other coins has very high exchange rate for example bitcoin go over 10k $ and to give the whole user a fraction of that as reward for ads watching will be hard so new coin will have low exchange rate and it easy to manage the share for the user reward

that my guess

have a nice day
