I don't think that is a problem.
It's strange that you are concerned about the privacy of the participants in the chat group, and at the same time some of their faces were shown in the thread you opened in the Bitcoin discussion. If you protect someone's privacy, you should do it in the right way.
As for the gold that someone has inherited, it obviously has sentimental value and at the same time it is insurance in case the family really needs a larger amount of money. I personally would not "gamble" with that, especially if I am someone who has just (perhaps) understood some basics, because as some other members have already mentioned, it is not just a matter of what the price of BTC will be in 1 or 5 years, but will that man manage to save what he invested long enough to make a profit.
Everyone should therefore think carefully and weigh the risks, because we don't want another story that starts with "I opened my crypto wallet and someone emptied it, what should I do?".
