Is there any scam coin on BINANCE?
No idea about this. When it comes to listing coins, I think Binance is very careful with listing coins. And not sure any scam coin would find its way into Binance
Nah. Even how Binance is very careful to check before listing, there are still a lot of altcoins that are listed on their exchange that may turn into SCAM or some of them are already scam but people still don't notice it.
Since at the first, how can we define a "SCAM COIN" at first? Can we tell Ripple(XRP) is a scam coin? Bitcoin Cash? It's kinda difficult to tell if there is no specification.
