I don't really give out advice to invest, I would rather tell them to save up in crypto rather than letting their excess money sit in their bank account.
I would also tell them the pros and cons of it, but I would never introduce crypto as a main source of income, if they would only rely on it, then they are risking their life on the line, not everyone could earn a stable income in trading and if it is their only money then it would be drained by their expenses.
This is truly the right advice to give to anybody, I mostly tell people that you should hold you savings in bitcoin as it is an hedge against Fiat inflation and if they ask me about the returns I tell them it is more less a bonus for them but I still warn them that the volatility that increases the price usually also dumps but a long term holders do have the advantage of avoiding this loss but yet still not guaranteed.
There is nothing wrong if he choose to come back to Bitcoin investment, perhaps that's why they say that every change in behavior or acceptance is as a result of experience so perhaps he has realized that if he had diversified his part of the salary into Bitcoin he would have gotten an investment to fall back on since he has lost his job but however if his motive on Bitcoin is to become rich overnight or an alternative of making money on a weekly basis is obvious he may not be ready yet because it will be very difficult or impossible achieving that, however I realized that most people who have not really venture into Bitcoin has a very wrong impression on Bitcoin investment because they feel that is very easy to start and begin to make money immediately.
I don’t think we need to reason anything about this because it is crystal clear that the person in question is looking for a source of income to balance up his Former lifestyle and bitcoin is certainly not that investment. The problem is that the kind of narrative that people have about bitcoin and cryptocurrency is sometimes bad; many people see this as a get rich quick scheme and once they have problems they refer here to double their investment which isn’t. So I don’t blame OP for the advice he dished out
