DeFi projects, in fact, the best way to promote is for the official team to share profits and arbitrage opportunities. For experienced players, there are many such opportunities that are rarely discussed. It is impossible to rely on players to share, because the logic of making money in DeFi is completely opposite to that of trading. In trading, people are willing to shout because it requires mutual support, while there are very few who are willing to talk about the real profitable mining/arbitrage opportunities. However, for the project team, this is the best advertisement.
