Crypto trader "White Whale" claims MEXC froze his $3.1 million account and demanded he fly to Malaysia for in-person verification to unfreeze it, as suggested by the exchange's global customer service head. Screenshots show MEXC also offered partnerships and perks, which he declined due to safety fears amid rising crypto kidnappings. Despite completing standard KYC, he launched a $2M NFT campaign on Base with a $1M bounty for supporters. MEXC cited freezes for manipulation but didn't confirm the invitation. Another trader reported $2M frozen since April. This underscores exchange risks.
