This is a very skillful and convincing scam. They will temp you in with very good returns and then when its time to withdraw there is a complicated bitcoin transfer that never works (there is an email from the bitcoin company (etherium) that says they need to see money in an account for security etc. rubbish – all fake and totally heartless. the ‘Brokers’ are extremely good at pulling you in and the trading site is probably scraped ( a new term i’ve learned) . please do not go near them. I’ve contacted various fraud agencies / banks etc. but they said they way its run it will be almost impossible to get any money back as based on bitcoin and all transactions are final. Look how the positive reviews are written. No one talks like that they are clearly fake. Please I don’t want you to go through what I and others have been though.
