They make me extremely nervous. Most people I know that use Robinhood seems to use it as they would play dices in Vegas. They have no ideas on the stock fundamentals or why and how the prices change. Most of them are playing a big amount of their savings too which is extra concerning.

What makes me even more nervous is that Robinhood seems to deliberately cater to those crowds of uneducated emotional day traders.

I said this before but they seem to become the "facebook of finance" with the same "break things and go fast" mission. I would never use them for any significant amount of money. That being said, I use them occasionally for options because the fees of traditional brokers are such a joke (20$ typically to sell and buy).
