The best way to promote DeFi projects is actually through official sharing of profits and arbitrage opportunities. In the eyes of veteran players, there are many such opportunities that no one talks about, and it is impossible for players to share them because the profit logic of DeFi is completely opposite to that of trading. Trading requires mutual support, and few people are willing to talk about the real profitable mining/arbitrage opportunities. However, for the project team, this is the best advertisement.
