My friend has made friends, family, girlfriend invest into bitcoin and people believed him because he has a successful online start up. Now their money is gone. I can imagine it's a little rough around the edges on communication, but ultimately it is up to the person that put the money in,
Can not blame him for that. He certainly wanted to give help and profit to those who advised them.
The price was not expected. No one can expect it
The gold rule is never to invest money which you can't afford to lose. I never give financial advises to my friend or close circles for exactly the same reasons mentioned by other users.
