Binance, the top cryptocurrency exchange in the world in terms of trading volume, has announced that 11 altcoins are currently facing the possibility of being delisted. On Monday, Binance added a “monitoring tag” to Balancer (BAL), Cortex (CTXC), PowerPool (CVP), Convex Finance (CVX), Dock (DOCK), Kava Lend (HARD), IRISnet (IRIS), MovieBloc (MBL), Polkastarter (POLS), Status (SNT), and Sun (SUN). Binance warns that tokens with monitoring tags are more volatile and risky than other cryptocurrencies, and the exchange conducts regular reviews of these tagged tokens. Binance users who want to trade tokens with monitoring tags must take quizzes every 90 days to ensure they are aware of the associated risks. Additionally, Binance removed Enzyme (MLN) and Horizen (ZEN) from its monitoring tag list. Enzyme is an on-chain asset management system, and Horizen is a privacy-focused blockchain network.
