However, this investor ultimately chose to exit when the price was 'halved', demonstrating the unpredictability of market volatility.

On the other hand, the first large purchase of WHY was initiated by address 0x03b7C1414857Ae0bCa09116d4A01175D4d9B86ad, also investing about $200,000.

This incident highlights the risks and challenges present in the on-chain trading environment.
