Was her car the only source of income? If that is the case, then she might have made a "risky move". Sure, if its going to pay off in the long run, but you should only invest what you can afford to lose. Invest your spare money, not your money that you will need in few days. If she is confident enough to get another job and able to lead a life without struggling, then yeah, she did the right thing. Assuming she doesn't fall for those FUDs, and cashes out only when she has reached her profit goal, then she will be doing fine. Nothing to worry about over here. Just tell her to make sure she knows what she is doing.
It is very unlikely that this is what's happening, people have a tendency to go all in when it comes a particular investment not realizing that you need to leave enough money for yourself and any emergency that may come up, otherwise when you are in a bad shape economically you are going to be forced to sell the assets in which you invested, now you may get lucky and sell your assets when they are very high in price and you get lots of profits but you are relying on your luck on that scenario.And as we know luck has a tendency of being completely terrible just when you need it the most, so I do not really think that we are going to hear positive things in the future about this particular story.
