Core Viewpoint - The demand for gold, particularly in jewelry, is rising, leading to some gold jewelry retailers engaging in illegal fundraising activities through various schemes [1]. Group 1: Illegal Business Models - The first model involves signing virtual contracts with customers, where they transfer funds for gold jewelry to the headquarters, which then offers a buyback agreement with promotional fees, typically with a one-year term and annualized interest rates significantly higher than bank deposit rates [2]. - The second model encourages customers to invest in shares of local stores, using a shareholding arrangement held by the headquarters [4]. - The third model operates under the guise of gold jewelry buybacks, establishing shell companies nationwide, promising principal and interest guarantees with full buyback and cash gifts after one year [6]. Group 2: Warning Against Fraud - Activities that promise fixed returns or guaranteed buybacks without delivering physical gold jewelry are considered illegal fundraising, and stakeholders are advised to remain vigilant [9].
