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!!!
This scam method has been around for a long time and I decided to block and report all of my DMs first and say that he is the admin of some project.
Money is never easy to find and the opportunity does not come to us easily. Be careful and wise, don't be greedy.
