I strongly disagree with this. Nobody can know beforehand what is a good investment or not. The omnipresent disclaimer applies: "All investments involve risks, including the possible loss of capital."
The idea that the professionals know something that the rest of us don't, is quite controversial and there are many articles giving evidence to the contrary.

This idea is also quite condescending (my own opinion, no references given).
Are you crazy? Robinhood just sent a message to retail investors (it's entire customerbase) that they are going to crush you at any given time. By using Robinhood your are exposing yourself to extreme risk of losing your investments no matter what stock you trade.
>Also, by making trading so easy RH has a responsibility to protect amateur investors from making terrible financial decisions.
WSB is about making terrible financial decisions as a sport. That's the entire point.
