Investing should be done with care and thought. Due diligence is required. At best, Robinhood's app and advertising portrays investing as easy, and at worst they portray investing as something to be done on a whim.
The act of buying a security should be easy, but the thought that goes into that decision is MUCH more important. They trivialize this aspect of investing in their advertising and app, which I believe is dangerous for the retail investors who don't know better.
