New: Bithumb Caution & Delisting Alerts

May 2, 2026

Last updated 2026-05-02

Your Bithumb feed now carries two trade-actionable risk events alongside listings: caution_released (caution designation lifted, often a positive technical signal) and spot_delisting (final removal from spot). Both travel over the same WebSocket connection as listings, with the same end-to-end delivery from our Seoul-based detection engine.

What we broadcast

We don't forward every Bithumb announcement. The feed is narrowed to three trade-actionable event types, all emitted on the same WebSocket connection:

"spot_listing"        // 원화 마켓 추가 — new KRW listing
"spot_delisting"      // 거래지원 종료 — final removal from spot
"caution_released"    // 유의 종목 지정 해제 — caution lifted (often a technical bounce)

caution_released is our event name for the moment Bithumb lifts a caution designation already placed on a token (거래유의종목 지정 해제) — the token had previously been flagged for review (concerns around liquidity, regulatory status, persistent volatility, etc.) and is now returning to normal trading status. spot_delisting is the inverse outcome: final removal from the spot market (거래지원 종료).

See the message reference for the full schema and example payloads.

Trading implications

Both events have a clear historical price-reaction direction: spot_delisting is bearish (final removal from the spot market) and caution_released is bullish (caution status lifted, the overhang of forced selling clears).

Detection & API

Both event types are delivered over the same WebSocket connection as listings, delistings, and airdrops. A typical caution_released message looks like:

{
  "type": "announcement",
  "title": "신세틱스(SNX) 거래유의종목 지정 해제",
  "ticker": "SNX",
  "publisher": "bithumb",
  "listingType": "caution_released",
  "detectedTimestampUs": 1745971200834000,
  "dispatchTimestampUs": 1745971200842117,
  "abnormalDetectionLatency": false
}

And a spot_delisting message:

{
  "type": "announcement",
  "title": "고트세우스 막시무스(GOAT) 거래지원 종료",
  "ticker": "GOAT",
  "publisher": "bithumb",
  "listingType": "spot_delisting",
  "detectedTimestampUs": 1745971200834000,
  "dispatchTimestampUs": 1745971200842117,
  "abnormalDetectionLatency": false
}

One detail worth knowing: a single Bithumb announcement frequently pairs a release with a delisting. A title like "신세틱스(SNX) 거래유의종목 지정 해제 및 (BCD, WTC) 거래지원 종료" simultaneously releases one ticker (SNX) and delists two others (BCD, WTC). We split these into two distinct WebSocket events with separate listingType values and deterministic IDs, so your bot can route each side independently — no parsing logic on your end. Multi-ticker, single-category announcements (e.g. "(BCD, WTC) 거래지원 종료") keep the listings convention: one event with the tickers joined comma-separated in the ticker field.

Filtering is a one-liner:

def on_message(ws, msg):
    data = json.loads(msg)
    lt = data["listingType"]

    if lt == "caution_released":
        clear_risk(data["ticker"])
    elif lt == "spot_delisting":
        unwind(data["ticker"])
