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