Well, long story short. I invested £250 and they kept asking for money over and over again. Which I thought was weird however they made it seem legit. They are asking for the last £100 to be able to transfer my 'profit' into my bank... however they asked for my email and made me a 'blockchain' wallet even though I said I have one. After a few days I couldnt access it. They told me it's because I havent made the last payment. Yet I told them I will make the last payment but I want access to my blockchain. So he again asked for my email, he set up another one... I think it's all fake and just a scam... everything seems weird about it. Also there was someone who said they would testify against it being a scam. So I spoke to her she convinced me to invest. Then she gave me the 'head of private key' number so I text , it was only her pretending to be this person. I asked her about it and she denied and blocked me off everything. They say they wont ask for any more money after every single time they do. Or I'll 'loose' my money. They are very rude and have called me names and blocked me on a few occasions, also there fb keeps disappearing like it never existed. He says it's because hes updating yet someone else from the 'company' have said so they dont get duplicated. It's all very weird and I'd avoid honestly. I regret doing it myself. I should have looked into it further first. Seems to be just a scam and dont want to put another 100 on it to try get my 'profit' for it to all be a scam.
