if I had that kind of money, I wouldn't risk asking people I don't know where to invest it, do a market analysis yourself and make a decision, because the amount is not small. I would pay attention to projects with their own blockchain and the top 10 CMC.
There is no harm in him asking, because here are many experienced investors so that every suggestion given he can draw conclusions on which coins are more worthy to invest with the capital he has, and as you said he also has to analyze the market himself so that no regrets arise if later the results obtained are not satisfactory, In addition to the top 10 CMCs he could also choose some decent memekoin at stake in the future.
