Binance users are receiving letters with an invitation to test a new application for Windows for a reward of 0.5 BTC, which 'will go to your Binance account. All you need to do is download and enter your data.
This is phishing! Attackers try to get personal data in this way, to access your money. Binance does not distribute 0.5 BTC for testing Windows applications. Be careful!
It's time to remember that no one and never just so much bitcoin or Ethereum does not distribute. Who has been in crypto for a long time, has seen more than one such fraud, and there are always too gullible people, and then everyone is told that crypto-currencies are scam.
