Upbit announced it will end trading support for Blur (BLUR) on Nov 30 at 15:00 KST, for BLUR/KRW and BLUR/BTC, with orders cancelled and withdrawals supported until Dec 30, citing unresolved investment-warning reasons from Oct 13. See Upbit notice here.
Bithumb posted a notice titled 블러(BLUR), 코어(CORE) 거래지원 종료, naming both BLUR and CORE for end of trading support. See Bithumb notice link here.
The Bithumb end date, pairs, and reasons could not be read because the Bithumb page would not load, and no mirror text was found in X or Telegram beyond alerts at 07:00 UTC Oct 30 and on Telegram.
So: Upbit delisting is BLUR only with Nov 30 date confirmed. Bithumb delisting names BLUR and CORE together, exact timing not confirmed in readable sources.
