of course this is not bad news for Monero, Monero still has great strength in various exchanges, Binance, MXC and Hitbtc are exchanges with the largest number of XMR trading volumes, maybe Huobi did not delete XMR in BTC or USDT pairs because I still saw in Coinmarketcap that XMR has a trading volume of $ 2 million / 24h, there is nothing to worry about it
