<prompt> Human: Hey I was wondering if 5000 USD would be enough to start investing. And if so, what would be the best way of doing it?  <response>: Yes. If you had 5000 income for the year, you could open an IRA and invest it in a market index fund. Youll have nearly maxed your annual contribution!Vangaurd is widely recommended as the best broker, due to their low fees.
