All I can say is some people have BIG cahones!!! All investments can go down hill no matter how well sourced and I would hate to be the person behind a decision like that And what do they say “… a woman scorned”
Joking aside though the above all seems very sensible My advice to new investors is simple, play only with spare money, read a wide range of opinions and learn. If in doubt stick to the ideas above or ETF’s.
My theory is most bad investors, not all, are greedy and want instant wins, live in echo chambers or don’t do enough research. If you don’t need to cash out in a short window then I find it is quite hard not to lose serious money if well spread and researched over time.
Edit - I know this will sound arrogant and I didn’t want to add but it is true/important. Some people are not clever/intelligent and not the “oh, but I have a degree” clever as many people with degrees I have interviewed for roles had less common sense than a clown but more aware of the world clever.
Take my nan, she was very intelligent in most ways and would have listened to advice but she would then think she knew how it all worked. All would be OK but then 2 years later I would find out she had spent a much larger sum on general investing gone bad. Why? Well, she will have decided that as she made 3% on bonds or something she would make some more on XXX as the news said it would go higher later She will have missed the point that it may come down much lower straight after.
