One of the major brokerages may cost you something in fees as you learn, but theyre not going to scam you out of your life savings.
And as I've said before, I would not rely solely only on a friend's recommendation, it's data that I value (or not) depending on my trust of the individual. And I'm well aware that many people -- and they can be neighbors or fellow club or church members -- get paid something when somebody they refer signs up.
I have to tell you, I am perplexed. We have one frequent poster here who, from what I can tell, gave pretty much ALL their money to a financial advisor more than 12 years ago (and has posted many times about it over the years), who promptly recommended half of it in the most non-liquid investment around, and nobody, no, nobody, no, not a single person here in all these years, have warned about eggs in one basket or get rich quick schemes or anything like that. But JFC, I post something about someone who did similar I get all this "don't put your eggs all in one basket", stick with Vanguard, Fidelity, major brokerages only, etc. I'm just not getting it.
