Personally I fund my IRA monthly up to $6k annual limit. Allocations are up to the investor and their personal risk tolerance but you can hold index funds, etfs, reits, individual stocks and more in there. I am much more aggressive in my Roth IRA than my 401k (strictly index and mutual funds) with some trading and significant crypto exposure percentage wise via GBTC and ETHE.
