| FAIR VALUE MEASUREMENT | 12. FAIR VALUE MEASUREMENT Measured at fair value on a recurring basis The Company measures financial instruments held, at fair value, cash and cash equivalents, crypto assets held, and long-term available-for-sale securities, on a recurring basis. Most of the Company’s financial instruments held, at fair value are classified as Level 1 since their fair value are determined based on the quoted market price. Some of the Company’s financial instruments held, at fair value that are valued at quoted prices in less active markets are classified as Level 2. Investments in private equity funds are categorized as Level 3 since they are valued utilizing third-party pricing information without adjustment. The Company classified its money market funds, which are presented in cash and cash equivalents due to high liquidity to be convertible to known amounts of cash and near maturity that they present insignificant risk of changes in value, as Level 1 since their fair value are determined based on the quoted market price. Crypto assets owned by the Group are presented in crypto assets held and classified as Level 1 since their fair value are determined based on the quoted market price. The Group measured the fair value of its long-term available-for-sale securities using a market approach and considered those as Level 3 measurement because the Group used unobservable inputs to determine their fair values. The unobservable inputs used were discounts for lack of marketability for such market approach (ranging from 15% to 20%), and the observable inputs used were risk-free interest rates (ranging from 3.5% to 4.5%), as of December 31, 2024 and 2025. Significant increases or decreases in any of those inputs in isolation would result in a significant change in fair value measurement. As of December 31, 2024 and 2025, information about inputs for the fair value measurements of the Group’s assets that were measured at fair value on a recurring basis in periods subsequent to their initial recognition is as follows:

FAIR VALUE MEASUREMENT (Continued) Measured at fair value on a non‑recurring basis The Group measures the equity securities without readily determinable fair value at fair value on a nonrecurring basis whenever there is an impairment indicator or any changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Group recorded nil and US$ 200,237 impairment loss related to the long-term equity securities without readily determinable fair value for the years ended December 31, 2024 and 2025. The Group performs a goodwill impairment test annually or more often if event occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carry amount. The Group did not recognize any impairment loss related to goodwill during the years ended December 31, 2024 and 2025. The Group measured acquired intangible assets using the income approach‑discounted cash flow method when events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. The Group did not recognize any impairment loss related to other intangible assets arising from acquisitions during the years ended December 31, 2024 and 2025. Key inputs and parameters primarily for the above impairment assessment include significant judgment and estimates by the management on future earnings, and discount rate. |
