Are there banks or investment advisors that can hold on to your money (and not lose it) for 10 years? Like you can quasi lock it in. Like would this be considered a trust or something?
Let's say I just want someone to take the S&P 500 and keep reinvesting it until I need it. How can you do this so you can't get easy access to it and someone else, reputable, keeps an eye on it?
