What is the advantage of AST?

Could you elaborate on the advantages that AST, or AirSwap Token, brings to the cryptocurrency and decentralized finance ecosystem? I'm particularly interested in understanding how it facilitates peer-to-peer trading, its impact on liquidity, and any security or trust features it might offer over traditional centralized exchanges. Is there a significant cost savings or efficiency gain for traders using AST? Additionally, how does it contribute to the broader decentralization movement in the financial world?
