Prominent crypto investor Sun Zeyu faces allegations of withholding $180 million in funds related to the TIA project and private investments. Sun, known for his roles as founder of Genesis Capital and Lancer Group, is accused of failing to deliver on investment commitments, leaving investors without recourse. Two separate disputes have emerged. In one case, investor Sunny William Lu claims a $300,000 investment in TIA tokens was never fulfilled, despite a signed contract. The tokens, which once had a potential value of $10 million, were never delivered, and Sun became unreachable post-transaction. In another case, Lu Zi alleges a $1.5 million investment was "liquidated" without evidence or documentation, highlighting the risks of informal agreements in the crypto space. These incidents underscore the dangers of relying on personal reputation over due diligence in the crypto industry, where cross-border transactions and anonymity complicate accountability. Both investors emphasize the need for caution, as trust-based agreements often lack the legal protections necessary to recover funds when disputes arise.
