Investment Risk Notice

• Investment in digital assets is exposed to sudden price fluctuations due to speculative demand and changes in domestic and international regulatory environments. Responsibility for investment decisions in this digital asset lies with you, and any potential losses are also attributable to the investor. We urge you to carefully reference the project's website and public disclosures to fully understand the characteristics of digital assets and trade prudently.

• Due to the nature of digital asset trading, price differences between domestic and international exchanges occur continuously. Always be mindful of such price differences with global exchanges before investing.

• Upbit takes various measures to ensure a stable trading environment, including a minimum order amount limit, but depending on the overheated market environment, some members may see an order stabilization message. This is an unavoidable measure to process orders placed earlier and ensure stable service, so please pay attention to this.

※ Virtual assets are high-risk products and may lead to the loss of all or part of your investment.
