This is a total scam, just as stated in several reviews. I feel stupid I didn't look at the reviews before. They convince you to invest and try to persuade you to invest more (which fortunately I didn't). When you wish to withdraw even a small part of your investment, your account is closed down, the email address they gave you doesn't work anymore and calls are broken of stating you have insufficient balance to complete the call. beware particularly of David Friedman: very helpful and charming, but then you can't reach him anymore. I was also called by somebody claiming to be from Investiva who told that the company was closing down operations in The Netherlands and he would help me to settle the account. This turned out to be an additional way of getting at your bank details and clear out your balance. It was a deeply frustrating and worrying situation, as my hard-earned money seemed to be stuck with no clear solution. Fortunately, I came across SEEKRAIL.cOM After sharing my situation with them, they took immediate action, and, to my relief, I was able to recover my entire investment
