you shouldnt feel that way. Everybody himself is responsible for their actings. You did not buy the stock with their money. They bought it.
I did the same. Sometimes these still good friends ask what the heck hapenned and I tell them the story from the crazy Lecrones, stealing the money, driving fancy cars, flying around the world screwing around, being at court and so on.
But in the end I say:
Stocks can rise or fall.
One good friend I also recommended the stock to said to me:
Simon, dont worry, I should have known when my bankguy said, oh this stock is listed on the
"you never get a dime back exchange"!
