Velika volatilnost tržišta kapitala i tržišta kritpovaluta, uz sveprisutnu inflaciju, stavlja pred investitore svakodnevnu neizvjesnost u povrat na svoju investiciju. Cilj ovog rada je bio istražiti prinos na investiranje u kriptovalute, kao visokorizičnu investiciju u usporedbi s investiranjem u S&P 500 indeksni fond, odnosno europsku inačicu Vanguard 500 indeksnog fonda, kao investiciju relativno nižeg rizika. Istraživanje je pokazalo da je, bez obzira na visoku volatilnost tržišta, na uloženih 10.000,00 USD portfelj kriptovaluta pokazao veći ostvareni prinos u odnosu na Vanguard 500 za 2.368,66% za razdoblje od 2017. do 2021. godine, odnosno za 1.150,75% za razdoblje od 2017. do 2022. godine. Investitori trebaju dobro poznavati karakteristike svoje investicije, rizike te moguće prinose. Uz dobru diverzifikaciju svog investicijskog portfelja, investitori mogu ostvariti zadovoljavajuće prinose uz smanjenu izloženost riziku. The high volatility of the capital market and the cryptocurrency market, along with the omnipresent inflation, creates an everyday uncertainty for investors regarding returns on their investments. The purpose of this paper was to research returns on investing in cryptocurrencies as a high-risk investment, compared to investing in the S&P 500 index fund, or the European equivalent, the Vanguard 500 index fund, as a relatively low-risk investment. The research showed that, regardless of the high market volatility, the cryptocurrency portfolio showed a higher return on invested USD 10,000.00 in relation to the Vanguard 500 by 2,368.66% from 2017 to 2021, i.e., by 1,150.75% from 2017 to 2022. Investors should have a good knowledge of the characteristics of their investments, the risks, and potential returns. With a good diversification of their investment portfolio, investors can generate satisfying returns with decreased risk exposure
