According to Wu Blockchain, South Korea's two major crypto exchanges, Upbit and Bithumb, both added Icon (ICX) to their trading watchlist on August 28 and suspended related deposit and withdrawal services. Bithumb stated that the designation was due to a security incident involving crypto wallets or distributed ledgers, with the cause yet to be identified or resolved. ICON, launched in 2017, is a Layer 1 blockchain, and ICX is its native token, primarily used for network transactions, staking, and governance in the past. Currently, ICON is transitioning to the cross-chain DeFi infrastructure SODAX. https://(wublock123.com)/news/upbit-bithumb-add-icon-icx-to-trading-watchlist-67386
