While the listing did not affect the price increase, I do not know why. But all the same, the price of Nem will grow with the entire market after recovery.
Yeah, it surprised me as well, but ~ 10 days after, we can see that the (Binance listing) affect of price level was "almost zero". Unfortunately, of course. Really dunno why -- probably it's because continuing bearish trend of bitcoin and most of altcoins are (now) clearly driven by BTC price level (and news & FUDs around that biggest cryptocurrency). God knows.
I - as most of people in this thread - also firmly believe, that NEM is far undervalued now and it deserved much higher price levels and much better CMC position (currently #15 place is really annoying). But when - and if - this would be repaired, this is really (at least) "one million question"
. Wish it will be soon...
