Hello competent investors, i am brand new to this so i got a robinhood account to invest in the vanguard s&p500. I have a retirement account with fidelity due to a previous job and i recently noticed an option to start a brokerage account on the fidelity app when i was checking my retirement. Ive seen a lot of hate on robinhood recently and was wondering if i should start a brokerage account with fidelity and ditch the robinhood?
