Most of the financial advise I have seen / followed has come from the posts on MMM. My general rule of thought has been to Max out employer match with self picked 401K allocations, Max my IRA / HSA, then Max the rest of my 401K. This is all based on that thought, that i wont need to touch any of this money for at least 30 years. A friend of mine recently informed me that 401Ks should not be used and instead I should be using a 7702. He said during a down market you get a guaranteed .75% return, and during an up market, you cap at 15%. Is this true? Can someone help me understand the difference between a 401K and the 7702, as well as the MMM communities general opinion of the use case for 7702 in regards to retirement. Thanks!
