Everyone that joins ICOs, bounties or airdrops might recently be receiving some emails purported to be from a project administrators informing you of that your earlier contact of the support has been escalated and you need to be a certain sum of bitcoin or ethereum in order to abade the problem otherwise, you lose your investment or earnings.
It is a scam. Beware!!!
Every investment that requiring ETH or BTC to be sent to the address other than the official one, are an obvious scam.
Another thing to do is we can confirm that the email is really from the team or not.
The email phishing method is quite effective targeting peoples with minimal communication to the project team.
