DO NOT, DO NOT INVEST YOUR MONEY WITH THIS GROUP/Company. Made the request to withdraw my funds and then a series of "fees needing to be paid" messages; the contact addresses no longer being valid, ie Nittrex.io and Nittrex.co and not informing their "clients of the recent changes," etc. Harry Silver, Charles Gaines and Steve Carter were the characters (fictional?) from Nittrex who scammed me and my wife of our life savings with their pseudo-concern for our future!
Unfortunately I'll never get my hands on them for a bit of payback out of their useless hides!
