Binance accounting bug leads to $20m misallocation of HNT tokens

As a result of misallocation of funds, Binance users mistakenly received tokens worth about ≈$20 million.
There are two tokens in the Helium network - HNT and MOBILE. Binance counted them as one - HNT, with the result that customers who deposited the less valuable MOBILE benefited. In simple terms, the exchange credited MOBILE tokens ($0.95) as HNTs ($4.2). In total, about 4.8 million MOBILEs were thus involved in the exploit.
