Binance distributed around 4.8 million HNT before discovering and patching the bug, valued at around $19 million.
Binance accounting bug involving Helium tokens results in $19 million of erroneous payouts
Helium has two different tokens: HNT, which is paid out to people who run Helium hotspots, and MOBILE, which is paid to those maintaining the new Helium 5G network. However, Binance erroneously treated both tokens as HNT within their exchange. As a result, anyone who sent MOBILE to Binance wound up with that same number of HNT tokens in their wallet — a big benefit, given that HTN has traded between $4 and $7 this past month, and MOBILE is not yet easily tradable.
