<prompt> Human: Im in my early 20s and have 3 questions I havent been able to find a clear answer for by doing my own research.1. Could you realistically open a Roth IRA with a one-time deposit say, 3,000 and then never make another deposit to it again until you withdraw it at 65 years old? Or are you required to continually make deposits to it?2. I know it would have to be a very rough estimate, but just out of curiosity, if you opened a Roth IRA with 1,000 at the age of 25, and then didnt contribute anything else to it if thats possible, how much could it possibly have at the age of 65? Im just curious how much doing the absolute bare minimum could get you.3. How much involvement do you need to have with Roth IRA investments? Is it a start it and leave it sort of thing, or do you need to check up on it make changes to it somewhat regularly? Just as an aside, I fully intend to contribute to it regularly, Im just asking these to get a better idea of how a Roth IRA works. Thanks!  <response>: Could you realistically open a Roth IRA with a one-time deposit say, 3,000 and then never make another deposit to it again until you withdraw it at 65 years old?

At minimum youd probably want to move the initial 1k out of the money market fund most IRA providers put your initial investment in.Please read the information found in the FAQ particularly I Have X ...
