What is portfolio diversification?

If you hold ten different cryptocurrencies, have you spread your risk ten ways? Not necessarily.

Think of a freelancer with many clients who all belong to the same company. If the company stops paying, the number of clients doesn’t protect them much. Something similar happens when different crypto assets depend on the same network, the same app or the same market trend.

Portfolio diversification looks both at where your money is allocated and at how closely the risks are linked. Correlation describes how much the prices of two assets tend to move together. The more they do, the less protection combining them may offer against a shared drop.

Why it matters

A problem in a specific project can hit a portfolio much harder if it relies almost entirely on that project. Diversification can reduce that dependence, without guaranteeing profit or protection from a broad market decline.

The weight of each position also matters. In a hypothetical €1,000 portfolio, if €900 is in one coin and the rest is split among nine others, the main exposure is still to the first one. The number of names alone doesn’t say much.

We find the question “what is each position exposed to?” more useful than “how many coins do I own?” Diversification can also span different asset classes, not just different cryptocurrencies.

What to watch out for

In periods of severe turbulence, many cryptocurrencies can fall at the same time. On top of that, correlations change: assets that moved differently in the past won’t necessarily keep doing so.

Custody is a separate issue. Different coins on the same exchange remain exposed to a possible problem with that provider. Conversely, the same coin held in different wallets doesn’t acquire a different price risk.

Finally, more positions mean more monitoring, potential fees and complexity. Even a stablecoin carries risks, such as losing its peg to the reference currency; it isn’t automatically a safe haven.
