The best way to support your favorite board is to buy its coins. In addition to becoming a co-owner of the board you are interested in and getting additional benefits from it (getting rewards, participation in governance, higher voting power, etc.), you will also make the board more attractive to all other users.
The more purchased coins a board has, the higher it is displayed in the rating of all boards, which means more people will notice it. Moreover, each purchased coin of the board increases the amount of the board rewards, making it more attractive and interesting for other members.
Users can also support boards by sending them tokens. You can send a donation to the board by tapping the Support button on the board page. 20% of the donated amount is sent to the board moderators and is shared among them. The remaining amount goes to the board fund.
Board moderators can use the board fund to award outstanding posts on their board. Such posts are highlighted in the feed with a special star next to the board avatar. The authors of such posts are rewarded with 300 tokens, which are taken from the board fund.
