Mr. Dave Clark, his assitant William Jackson and their employee Ms. Mary (she also says her name is Lise Whitely) are all FRAUDS. They claim to be expert Forex traders in Bitcoin mining working for a company called Nasdaq traders. They are not legit. They will fool you to pay some minimum amount first guaranteeing you a profit after 4-5 days. Later they will ask you to pay some more for Upgrade of the account.Even when you pay for the upgrade, you still have to pay more for VAT code and this never ends..You will just keep paying and they stop responding in some. All your money is lost. There is no way you can recover it . PLEASE dont invest with such FRAUDS.
