On investment platforms you will find three similar acronyms today: ETF, ETC and ETN. They differ by a single letter and are often confused, yet behind each is a different legal construction, a different risk and in some cases different tax consequences. For a Slovak crypto investor the difference matters especially, because the product they buy as a "Bitcoin ETF" is usually not an ETF at all. In this article we explain how these three instruments differ, where they came from, where you will run into them and how they are taxed in Slovakia.
The common denominator: they are all ETPs
Let us first sort out the acronyms. The umbrella term is ETP, an exchange traded product. It is the roof over all three instruments. What they share is that they trade on an exchange like a share, they track the price of some underlying (an index, a commodity, a cryptocurrency) and they try to follow it as closely as possible. The difference is in what exactly you buy: a share in a fund, or a debt security.
ETF: a fund that actually holds the assets
An ETF (exchange traded fund) is an exchange traded fund. When you buy a unit, you become a co-owner of a basket of real assets the fund holds: shares, bonds, possibly a physical commodity. The fund's assets are separated from the manager's assets, so if the manager went bankrupt, your units remain yours. That is exactly why an ETF is considered the safest part of this family.
In Europe most ETFs fall under the strict UCITS regulation, which requires diversification and protects the investor. A typical example is an ETF on the S&P 500 index, which holds the shares of 500 US companies in a single instrument. This combination of real backing, segregated assets and regulation makes the ETF the standard for long term passive investing.
ETC: a debt note tied to a commodity
An ETC (exchange traded commodity) looks like an ETF on the outside but is completely different inside. It is not a fund but a debt security, usually issued by a special purpose vehicle (SPV). It originally appeared to track commodity prices that are hard to hold via a classic fund: gold, silver, oil, gas.
A good ETC is backed either by a physically stored commodity (gold in a vault, for instance) or by other collateral, and it has protections built in for the case of issuer default. Even so, you are not buying a share in a fund, but a claim against the issuer. An ETC does not fall under UCITS, so it can track a single asset, which a fund with mandatory diversification cannot. That is how the structure later spread to currencies and finally to cryptocurrencies.
ETN: a debt note built on the issuer's promise
An ETN (exchange traded note) is also a debt security, even closer to a bond. The issuer, usually a bank or financial institution, undertakes to pay you a return based on the underlying, less fees. The original ETNs were not backed by any specific asset and rose and fell purely on the creditworthiness of the issuer: if the bank went bankrupt, the note could lose value regardless of how the underlying performed.
Modern crypto ETNs are better off, as they are usually physically backed by actually purchased cryptocurrencies held in custody, but formally they are still a debt instrument, not a fund. This is precisely the category most European "crypto funds" belong to. The line between a crypto ETC and a crypto ETN is in practice thin, and issuers use both names almost interchangeably. What matters is that in both cases you hold a debt security, not a share in a fund.
Quick comparison
A bit of history
The evolution of these instruments neatly mirrors how investing gradually opened up to ordinary people. The very first ETF in the world was born in March 1990 in Canada on the Toronto exchange: the TIPs fund tied to the 35 largest Canadian shares. The more famous US SPDR S&P 500, still one of the largest funds in the world, followed in January 1993.
Commodities came later. The first exchange traded products on gold appeared around 2003 to 2004. The ETN category as a distinct type was popularised by the bank Barclays in 2006, when it issued the first two notes tied to commodity futures. Crypto is the youngest of all: in the US the first spot Bitcoin ETFs only launched in January 2024. In Europe regulation still does not allow full spot crypto ETFs, so crypto ETNs and ETCs play that role here instead.
Where you will run into them
You will meet ETFs at practically every broker that offers share investing, from Interactive Brokers through XTB to Slovak banks. Crypto ETNs and ETCs can be found for example in the XTB offering, which lists them for Bitcoin, Ethereum and for baskets of several cryptocurrencies from well known issuers such as VanEck, 21Shares or Bitwise.
On the platform they often show up labelled as Bitcoin ETN or under tickers like BTCE.DE and VBTC.DE and trade on the German Xetra exchange. An important detail: although many call them "Bitcoin ETFs", legally they are ETNs, that is debt securities, not funds. And one more warning when buying: make sure you do not buy a CFD on the same asset instead of the actual ETN. A CFD is a speculative leveraged instrument unsuited to long term holding or to the time test.
How it is taxed in Slovakia
And now the part investors care about most. For a Slovak individual a simple rule applies: ETF, ETC and ETN are all treated for tax the same way, as a security. Even though they differ markedly in structure, what matters for income tax is only that it is a security admitted to trading on a regulated market. And the so called time test applies to those.
If you hold such a security for more than one year and do not have it in your business assets, the income from its sale is exempt from income tax and from health contributions under § 9 ods. 1 písm. k) of the Income Tax Act. The rate is 0 percent. If sold within a year, the gain is taxed like shares (19 or 25 percent plus 16 percent contributions), and you can apply an annual 500 euro exemption on the gain.
Here is the decisive contrast. If you held the same Bitcoin directly, that is in your own wallet or on an exchange like Binance, there would be no time test and the gain would be taxed progressively at 19 to 35 percent plus 16 percent health contributions, up to about 51 percent in total. Through a crypto ETN on a regulated exchange you reach 0 percent on a holding longer than a year. The difference between "I own Bitcoin" and "I own a security tied to Bitcoin" can therefore amount to tens of thousands of euro.
Let us put it in numbers. Imagine a gain of 30,000 euro after more than a year of holding. With direct Bitcoin as an individual you pay, in the lowest band, 19 percent tax (5,700 euro) and 16 percent health contributions (4,800 euro), 10,500 euro in total, and keep 19,500 euro. At higher bands it can be considerably more. The same gain through a crypto ETN held over a year is exempt, so you pay 0 euro and keep the full 30,000 euro. That is a 10,500 euro difference on a single trade, purely because of the form of exposure you chose.
A few caveats so you do not get burned. The exemption only applies to securities admitted to trading on a regulated market, so off-exchange certificates, leveraged or inverse products, or purchases made off-market may not qualify. Since 2024 the year must moreover pass not only from purchase but also from the security's admission to the regulated market. With ETNs you also need to keep in mind that a sale of the note on the market is what is exempt, not its eventual redemption at maturity. And note: the tax authority once published and quickly withdrew a contested opinion on ETF taxation, so for larger sums it pays to keep your records in order.
And what about a company (s.r.o.)?
For a company there is almost no distinction between ETF, ETC, ETN or direct crypto. A company has no time test, every realised gain enters the tax base and is taxed at 10 percent (for taxable revenue up to 100,000 euro per year), with no health contributions. Distributing the profit to the owner adds a further 7 percent dividend tax. For active traders and higher volumes a company tends to remain the most advantageous, while for passive long term crypto exposure an individual via an ETN with zero after a year wins.
What to take from this
The structural difference between a fund (ETF) and a debt note (ETC, ETN) is mainly about risk, not tax. With an ETN you carry issuer risk: if it went bankrupt, do not expect money from the bank guarantee fund. So when deciding, weigh mainly the backing, the fees and the issuer's credibility. For tax, in Slovakia all three are essentially the same.
An ETF is a fund that actually holds the assets and tends to fall under UCITS. ETC and ETN are debt securities where, instead of a fund unit, you hold a claim against the issuer, and in Europe the path to crypto exposure runs precisely through them. For a Slovak individual all three are taxed as a security, so after a year of holding on a regulated market the sale is exempt. Compared with direct crypto, which for an individual has no time test and climbs up to 51 percent, that is an enormous difference.
This article is a general overview, not individual tax advice. Whether a specific product qualifies for the exemption in your case depends on its structure, where it is traded and how you record it.
