According to the official announcement, South Korea's largest crypto exchange, Upbit, and the second-largest crypto exchange, Bithumb, announced on August 24 that The Sandbox ($SAND) has been designated as a 'watchlist asset' due to unresolved security incidents, such as unidentified or unaddressed hacking attacks on its wallet or distributed ledger. Bithumb is expected to review between September 28 and October 2 whether to remove the watchlist designation, extend it, or terminate trading support. https://(wublock123.com)/news/upbit-bithumb-add-sand-to-watchlist-over-unresolved-security-incident-67084
