Gatecoin.com

Gatecoin.com (CEX)

Gatecoin.com is best understood as a research/dataset label for a second address cluster attributed to “Gatecoin” (Gatecoin.com)—not a distinct, legitimate exchange brand with its own functioning domain.

What it refers to

• In academic blockchain-entity clustering tables, “Gatecoin.com-2” appears as a separate entry under the “Exchanges” category, indicating another identified cluster of Bitcoin addresses associated with Gatecoin. (pdfs.semanticscholar.org)

Underlying entity: Gatecoin (historical)

• Gatecoin was a Hong Kong-based centralized crypto exchange that later wound down operations following a court winding-up order (March 2019). (cryptoninjas.net)
• Data aggregators also note Gatecoin has shut down and is under liquidation, reinforcing that the original exchange is defunct. (coingecko.com)

Bottom line: Gatecoin.com-2 = “Gatecoin (exchange) — second clustered entity in a dataset,” not a separate live CEX accessible at gatecoin.com-2. (pdfs.semanticscholar.org)
