1. Insufficient purity: The purity of gold from the Millennium may not be high enough to meet the gold collection standards of some jewelers or financial institutions. Purity is one of the important indexes of gold jewelry. The higher the purity, the higher the value of gold.

2. Unstable quality: The processing technology and process control of Millennium Gold may not be stable enough, resulting in unstable quality and certain risks. Therefore, some merchants may be reluctant to buy century gold.

3. Lack of trust: Due to the relatively low brand awareness and market share of Millennium Gold, some merchants may have doubts about the quality and source of their gold, so they are reluctant to buy it.
