I wouldn't "encourage" anyone.
If a friend come and asks for some informations I'll gladly provide.
But i really don't want to bear any responsability in one's investements.
This is something that I have been thinking for some time, in one hand I will like to help my friends to invest their money and get profits but at the same time if they lose I do not want to have any kind of responsibility for their losses, that will put a lot of strain in our relationship, so for the time being I have decided to stay silent and only comment about bitcoin if they ask me questions.
