There's alot of speculation around NANO right now... Apparently people saying Binance only added NANO when a big dip happened and after they bough the dip... not good. Also supposedly NANO was added to Binance 1h ago but people can't trade it still and all those who sent NANO to binance didn't receive it yet. I also heard that the fee of withdraw is 1 NANO

Yes, it so strange that more than 1 h but not possible to trade. Never seen such thing on Binance.
As you saying, all those rumors might be true and its not good.
