Sounds too good to be true in my ear, this is absolutely what newbies like, they like taking useless risks like this one, someone telling you to make deposit so you can get double of your deposit back is a scam, another example is buy gold or valuable item at a unbelievable low price should be alarming to you
Yeah, newbies should be alerted about something like this. It is the most common trick of scammers to fool newbies. The sentence "too good to be true" always need to be in your mind. When somebody gives you an unbelievable offer sounds too good, just skip it! You rather skip the opportunity once (which is most likely a scam) than be fooled and lose your money!
