Just like in every real-world discussion, being an extremist/maximalist is never good, especially if you don´t accept other people opinion.
In the investments business, one of the most important rules is to not put all your eggs in the same basket. But, as you said, buying the "king" is the safest and most easy way to bring new people into cryptocurrency.
Great point about not putting all your eggs in one basket!! I should have made that point in my video. haha It's true though... diversification is usually a safer bet.
Exactly, diversification is the safest and best way to go, especially for those who don´t like to or don´t have the time to do intensive research and follow the markets closely.
