AI stocks alongside crypto.

Crypto and growth equities are both sensitive to the price of money. When rates fall and capital is plentiful, money flows to assets whose payoff lies far in the future. When rates rise, that same capital retreats from both at once.

In calm periods prices diverge on their own news. A halving or ETF flows for crypto, an earnings report for equities. But in stressed weeks, exactly when diversification should help, correlations rise.

A share is a claim on the profits of a business with revenue, costs and an accountable board. A crypto asset is a network asset without a profit and loss statement, valued on usage, scarcity and confidence.

The plumbing differs too: shares sit with a broker under investor protection, crypto can be self-custodied with all the freedom and responsibility that implies. Crypto trades every day of the week; equities do not, which changes how weekend shocks propagate.

Start from the share of wealth you are willing to put at risk, and only then split it. A common approach is a core of broad index funds with a limited satellite covering thematic AI and crypto together, rather than giving each a large weight separately.

Write down your maximum weight per bucket before you buy and rebalance on fixed dates, for example twice a year. That forces you to sell after strong gains and buy after falls, exactly when instinct says the opposite.

Owning a world index fund, an AI ETF and shares in a crypto exchange or miner often means holding the same risk three times. Listed miners and trading venues track bitcoin closely, while AI ETFs largely contain the same large technology firms as the world index.

Once a year, look through your funds: list the ten largest underlying holdings next to your single stocks and crypto. Most people find a concentration they never consciously chose.

In the Netherlands both fall under box 3, with practical differences around valuation on the reference date. In Belgium the question for both is whether you invest as a prudent person or speculate, with stock exchange tax on top for share transactions. Our tax guides go deeper.

Keep purchases, sales and costs in one overview per category, in euros. It saves work at filing time and shows your real return after costs.
