Kripto para birimi fiyatlarının tartışmalı yükselişi, bu varlıkların finansal sistemin geleceğindeki rolü ile ilgili görüşleri kutuplaştırmıştır. Piyasa etkinliğine dair en kritik göstergelerden birisi olan fiyat balonları, piyasanın geleceğine dair yapısal ipuçları taşımaktadır. Bu çalışmanın amacı, dünya çapında kripto-borsalarda işlem gören kripto para birimlerinde spekülatif fiyat balonlarının varlığını araştırmaktır. Bu amaçla piyasada en çok işlem gören 8 kripto para biriminde spekülatif fiyat balonlarının varlığı, günlük frekansta veriler kullanılarak, 1000 tekrarlı Monte Carlo Simülasyonu ile doğrulanan Sup-Augmented Dickey-Fuller testine tabi tutulmuştur. Analiz bulgularına göre, fiyat seviyelerinin spekülatif fiyat balonu olarak nitelendirilebileceğine dair bir bulguya rastlanmamıştır. Öte yandan, fiyat seviyelerinin bu varlıkların içsel değerlerinin üzerinde seyrettiğine dair bulgular, piyasada spekülatif olmayan fiyat balonlarının varlığına işaret etmektedir. Bu sonuçlar kripto para birimi fiyatlarının ani bir fiyat düşüşü yerine kademeli olarak düşüş yaşayacağına dair bir işaret olarak yorumlanmıştır. 

Bu çalışma, güncel finans literatürünün en tartışmalı konularından birisi olan kripto para piyasalarında fiyat balonlarının niteliğini spekülatif açıdan ele alması açısından literatüre katkı sağlamaktadır.
