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).
In fact, I know in the US you need to be an accredited investor for some times of investment for exactly this reason - it is so easy to get ripped off.
