Thanks for all that info Lauren. The thing with this is, even if it seemed impossible to me (10% a day), you have some hope, that you are one of the few who is going to take advantage. When you get contacted the first time with that kind of offer you think all but realistically. From now on I will of course know, but it's a totally different thing the first time.
I think the thing that saved me was the fact I already invested in Bitcoin and her offer was very suspicious, but I was hoping this was a new method and so on... You start dreaming but you shouldn't I know

Anyways this is a closed case, I hope others learn from it as well and thanks everyone for the help!
Always ask yourself, why just a random guy on internet will find you somehow and give you free money?
Same as the Nigerian prince... My cousins won a couple of millions from a lottery he never participated in, then those guys called him from Canada that they need a his bank accont to transfer the prize but they needed some small amount to open a account. He just said, use the money from the reward to open it.. and guess what, they never called again.
