Upbit and Bithumb are ending spot trading support for ZIL. Upbit stops its ZIL/KRW and ZIL/BTC pairs on Nov 16 at 11:30 AM IST, and withdrawals stay open for about 30 days, until Dec 16. The reason is unresolved problems flagged in a July trading-caution warning, which concerned wallet and ledger security risks.

$ZIL is a mid-cap in the CoinMarketCap top 400, and losing both major Korean exchanges is a big hit to its trading liquidity.
