Pionex Will Delist OBT, SPA, and KOMA Spot Trading Pairs

Dear Users,

Pionex will periodically review each digital asset we list to ensure that it keeps the high standard level we expect. When a coin or token no longer meets this standard or the industry changes, we conduct a more in-depth review and potentially delist it.

When we conduct these reviews, we consider a variety of factors. Here are some that drive whether we decide to delist a token or coin:

• The commitment of the team to the project
• Level and quality of development activity
• Trading volume and liquidity
• Stability and safety of network from attacks
• Network / smart contract stability
• Evidence of unethical/fraudulent conduct or negligence

According to the above factors, we will delist and cease trading on the following token at 03:00 on December 19th,2025(UTC) :

• OBT, SPA, and KOMA

Please note

• Delisting pairs: OBT/USDT, SPA/USDT, and KOMA/USDT.
• At the same time as the above-mentioned trading pairs are delisted, the bot orders and manual orders of the corresponding trading pairs will be canceled. The orders containing OBT, SPA, and KOMA assets in the rebalancing bot will not be canceled, and the OBT, SPA, and KOMA positions in the rebalancing bot orders will be released.
• The OBT, SPA, and KOMA positions will be sold at the best available price after they are delisted, and the USDT will be reissued to the users' holding accounts. If you are worried about price fluctuations, closing the bot in advance or selling them manually is recommended.

Risk warning:

Trading in the crypto market carries a substantial risk and the possibility of making both significant profits and losses. Please trade cautiously. Though Pionex will make its best efforts to choose high-quality assets, Pionex could not assure any profit and will not be responsible for your trading loss.

Thanks for your support!
