Its not delisted. Stp lying pls
I'm not sure about Yuanbao, but Jubi delisted NEO. You can see it yourself:
https://www.jubi.com/coin/ans/. Trading is suspended and there is a notification in red above the chart. Yunbi, 19800 and 51szzs echanges delisted NEO even earlier.
If Bitfinex hadn't listed NEO, it could fall much lower.
