My thoughts on these kinds of things are heavily influenced by Harry Brown's permanent portfolio, which is a 25/25/25/25 weighting of cash/bonds/gold/stocks. The basic idea is that in different economic environments, different asset classes outperform. So when one does well you can reap the gains from the winner and rebalance them into the losers to reset for the next economic season.

This kind of approach has done very well over the last 40 years or so. It underperforms 100% stocks by about a point, but you get much less volatility.

if you are just looking at one year, it's not so important to get things exactly right. Only crypto is volatile enough to return really meaningful gains on 1M USD, but it could go either way!

So for me, a portfolio would look something like this:

Cash: 20%

Gold/Silver: 10%

Real Estate: 30% - real estate would be rental real estate that is generating yield

Stocks: 15% - and this would be dividend payers like the dividend aristocrats

Crypto: 25%

Crypto and gold/silver actually perform a similar function. They aren't investments per se. They are savings in competing currencies. If your national fiat goes down too far, the alternative savings compensate.
