BNT is absolutely scam coin. It was listed today on Yobit and there was a short-run pump and then classic dump (from 2991 to 100 sat). And it's not the end, it will go to 1 sat very soon. There is also an invest for this shitcoin (another sign of scam) and there are limits at invest - min 100 and max 75000, so you can't check how many coins are in invest box (another attribute of scam). So I would't recommend anyone to buy this shit - it will be delisted very soon. There is another coin - Bancor (BNT), you can find it at coinmarket, so I guess the developer of this NBT SHITCOIN used similar name to confuse traders.
