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. For more on this topic, see HSA Triple Tax Advantage.

Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error. For more on this topic, see Community Building.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.
