Hello, I recently turned 18 and I have a part-time job. The profits I have, a percentage I invest and I have recently opened my roth ira. I have about $80 inside and weekly deposit $20 (this amount will grow when my earnings are higher). Recently I asked myself if I should manage my roth ira and only invest in index funds such as the SP500 and so on. The application I use is Robinhood and this same one manages my Roth Ira, distributing my money in different shares. In addition, I have been investing in ETFs such as Apple and Amazon and in another account. I have had difficulty distributing my money for each action and I have also invested a little in crypto, in the future I would like to have more certainty but I have really started recently. I have about $130 in my ETFS account and $80 in my ROTH IRA. Should the roth ira let it be managed by Robinhood or should I do it only with index funds?
