A kriptovaluták piacának dinamikus fejlődésével párhuzamosan fontos pénzügyi és közgazdasági kérdések merülnek fel. A jelen kutatás fő fókusza a kriptovaluták árfolyamának alakulására irányul. A szakirodalmi bázis feltárása nyomán kiemelt figyelmet kapott a kriptopiac más eszközosztályok (arany, részvény, deviza) piacával való összehasonlítása, a kapcsolódási pontok azonosítása. Ezt követően a cikk a 2020 utáni időszakra fókuszálva, eseményelemzés (event study) segítségével igyekszik feltárni, hogy a két legnagyobb piaci kapitalizációval rendelkező kriptovaluta (a bitcoin és az ethereum) hogyan reagált néhány választott eseményre. Ez elsősorban a kriptovaluták működésének alapját képező rendszerek elleni hackertámadásokat jelenti, illetve a szabályozásukhoz, az alkalmazásukhoz kapcsolódó egyes lépéseket. Összességében megállapítottuk, hogy a hackertámadások nem hatottak szignifikánsan a két vizsgált kriptovaluta árfolyamára. A szabályozói lépések hatásai az árfolyamokra vegyesek, ám a szignifikáns hatások is rövid lefolyásúnak tekinthetők.
