The fluctuation of their values is very unpredictable, so the periods of growth are often abruptly interrupted by stagnation or a pronounced decline. Nevertheless, a large number of investors have been involved in the processes of mining and trading cryptocurrencies in recent years. When it comes to the negative aspects of cryptocurrencies, the focus is primarily on various forms of cybercrime. The number of hacker attacks using the blackmail software - ransomware, is on the increase. In such cases, cryptocurrencies are often used as a means of paying ransom. However, the energy efficiency of certain types of cryptocurrencies is a less common topic. The Proof-of-Work (PoW) algorithm used for mining in some systems is an energetically intensive and really expensive process, which after economic analysis no longer seems as profitable as it first appeared to be. Cryptocurrency trading could bring a great income to the investors, but also great losses, because it essentially represents a zero-sum game. The sudden increase in the number of miners led to the disturbance on the computer components market, causing the price increase and even the complete disappearance of certain graphics card models. Everything previously mentioned indicates that cryptocurrencies have brought many negative aspects and disturbances. The subject of this paper is the economic aspect of cryptocurrencies based on the PoW algorithm. The aim of the paper is to indicate the economic unsustainability of their current concept, due to the high costs borne directly by participants in the mining process and indirectly by participants in the computer components market. Uspeh različitih sistema kriptovaluta uslovio je veliko interesovanje za njihovo funkcionisanje. Kretanje njihovih vrednosti je veoma nepredvidivo, pa su se periodi rasta često naglo prekidali stagnacijom ili izraženim padom. I pored toga, poslednjih godina se veliki broj investitora uključio u procese rudarenja i trgovine kriptovalutama. Kada se govori o negativnim efektima koje kriptovalute stvaraju, u fokusu su različiti oblici sajber kriminala. Broj hakerskih napada upotrebom softvera za ucenjivanje - tzv. ransomvera se povećava. Po pravilu, u ovakvim slučajevima se koriste kriptovalute kao sredstvo plaćanja otkupa. Međutim, energetska efikasnost određenih klasa kriptovaluta je nešto ređa tema. Rudarenje po Proof-of-work algoritmu (PoW) je energetski intenzivan i izuzetno skup proces, koji nakon ekonomske analize ne deluje isplativo kako se u prvi mah činilo. Trgovanje kriptovalutama može da donese velike prinose investitorima, ali i velike gubitke, jer u suštini predstavlja igru sa nultom sumom. Nagli rast broja rudara doneo je poremećaj na tržištu računarskih komponenata, izazvavši rast cena i čak potpuni nestanak određenih modela grafičkih kartica. Sve navedeno ukazuje da je njihovo funkcionisanje donelo brojne negativne manifestacije i poremećaje. Predmet rada je ekonomski aspekt kriptovaluta zasnovanih na PoW algoritmu. Cilj rada je ukazivanje na neodrživost njihovog aktuelnog koncepta, usled visokih troškova koji se stvaraju direktno učesnicima u procesu rudarenja i indirektno na tržištu računarskih komponenata. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: Bosnian refInfo: holdings: @attributes: islocal: N |
