I was told by someone that I know the last month and never met in person about an investment opportunity. Before you tell me that I am an idiot, how I was involved with this person and the reason that I trusted her is another discussion.
Almost all the tokens backed by ico are shitcoins and scams. We used to see how people lost their money investing in a coin called "promising", but trusting someone that you didn't ever meet with 0.5 btc is the most interesting part of your story. I think you bought the coin because you trust the person who told you about it and not because you beleive in the project itself especially after you found no review about the exchange. I think it's important to mention if the girl belong to scam team or she is a victim like you.
Sorry for your lost mate. You should take more care about who to trust and where to send your money.
I think is easier said this way, he needs to move on and don't fall again for things like this.
Some of us have made some now foolish mistake of investing in ICO. We now understand better not to invest in such levels of start ups because anything can happen and the team decides to go under.
