It's an old trick.
But people still do, and I wonder where they get our email addresses.
there are many factors,
for example ;
if you are using bot or any 3rd party application and at the same time it's linked into your Binance account,you will get this absolutely.other than this it should be because of malware,phising and do not forget the Binance itself.Do not get me wrong and accusing them as a scammer,but we should know what is greed right ?
people will do everything in order to get benefits from their action(for example just like Binance did when they listed BCN on their website).
so many factors that can be determined.
just make sure you do not click it or download it
