Be Aware Of Coin Jar

My mate purchased a portfolio of various cryptos including ethereum through some site called Coin Jar. He invested $17,000 into the portfolio. When he wanted to withdraw a portion of the funds they asked him for $100 to withdraw so he paid it. Then another $200 for "account fees" and then finally they were saying they were experiencing "difficulties" and asked for a further more $500. By this point he'd realised he had fallen victim to an elaborate scam. Reported it to his bank and the bank said as the funds had been converted into crypto the money was unrecoverable. However now they're under investigation. Steer clear and be weary of these scammers. They're getting very clever now creating online trading platforms.
