Faced with any investment opportunity—Bitcoin, stocks, real estate, a business—apply these four criteria in sixty seconds: capital preservation, tax efficiency, cash flow, and growth. If they don’t pass these four filters, keep looking. And before investing, apply the Four Goods test because scams don’t come with a warning.

The market is a machine for transferring attention from the asset to the noise. Every time an opportunity appears, your brain activates FOMO and shuts down analysis. The sixty-second protocol exists to deactivate that response.

The first filter is the most basic and the most ignored: how likely is it to lose the principal?

Not all risk is bad, but you need to know exactly what you’re exposing yourself to. Government bonds and diversified ETFs offer high preservation. Cryptocurrencies without a track record and early-stage startups offer low preservation. The question isn’t how much you can earn. It’s: if this asset loses half its value tomorrow, can I afford to wait?

The second filter separates professional investors from dilettantes: how much does the government keep?

It doesn’t matter how much you earn; it matters how much you keep after taxes. Real estate offers depreciation and other tax advantages. Short-term trading and savings account interest do not. An asset with high gross returns but low tax efficiency can be worse than one with moderate returns and high efficiency.

The third filter is the investor’s oxygen: does this asset pay me while I wait?

Rent, dividends, and royalties generate cash flow. Land speculation, art, and physical gold do not. The key question is whether this asset pays you every month or you’re just hoping someone will buy it from you for more later.

The fourth filter looks at the horizon: will the value of this asset grow above inflation in ten years?

Asset	Preservation	Tax Efficiency	Cash Flow	Growth
Real estate (rental)	High	High	Yes	Moderate
Bitcoin	Low	Medium	No	High
S&P 500 ETF	High	Medium	Yes	Moderate
Your own business	Low	High	Yes	Very high

Before investing in anything, audit the person behind the deal.

The Four Goods filter what the numbers can’t measure. Have you verified the person? What do those who have worked with them before say about them? How do they behave under pressure? Do the numbers make sense in cold analysis? Does the contract protect you, not just the other party? If any of these four fail, don’t invest.

Take sixty seconds. Rate each criterion from one to ten. If the average is below seven, don’t invest. Apply the Four Goods to whoever is offering you the deal. If everything passes, then consider moving forward. This protocol will save you years of regret.

When the asset has passed the four filters, the next step is deciding how to buy it without taxes devouring the returns: the smart debt strategy the ultra-rich use and the seven laws of money that separate the 0.01% elite from the rest give you the rest of the map.

Frequently asked questions

What are the four criteria of the Investment X-Ray? Capital preservation (risk of losing the principal), tax efficiency (how much the government keeps), cash flow (pays you while you wait), and growth (appreciates above inflation).

What are the Four Goods? A filter to audit the person behind the deal: good people, good intentions, good rationality with numbers, and good contracts that protect you legally.

What’s more important: cash flow or growth? It depends on your stage. If you’re building capital, prioritize growth. If you already have capital and are seeking freedom, prioritize cash flow.
