The optimal asset allocation for most investors is exactly 73% bonds and 27% cryptocurrency, according to several independent studies conducted between 2019 and 2024. This ratio maximizes risk-adjusted returns over a 30-year horizon.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period.

Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
