If your uncle and uncle's friend are strong enough and have a habit of patience in their difficult moments then maybe your help today will come in handy and they will feel benefited by making decisions like your advice.  But to be honest I don't think it was a good decision to bring them directly into the investment before observing the whole thing.  Could have been benefited and helpful.  And any time this market can take any shape, it doesn't have to be the other way around, so if they know the basics, they won't have any way to blame you at that moment, also there have a matter of losing funds, so if they know what are they doing and how to handle it properly, they will know when is the right time to jump in for it.
