There is no surprise on that case. It is already expected that many people will took advantage of others just to have the credentials of having money in terms of Bitcoin for their own sake. That is why we Bitcoin owners, holders, users as well as investors must assure that our accounts are in good state and not easily trust the sake of your Bitcoins into other people. Better check first the credibility and reliability of the people we are trying to entrust our Bitcoins because it is hard or worst impossible to retrieve or get back what have been loss once you have already put it into the wrong hands of those people that tends to scam other people just to obtain what they want. Nevertheless, trust no one because Bitcoin as we all know is really that valuable in this market so we must secure it and be responsible enough on handling it on our accounts to avoid being scammed by other people. Be wise on decision making and be careful as always.
