This paper uses a theoretical model to analyse the dynamic relationship of virtual currency with fiat currency. The model demonstrates that the price impact of potential users and speculators in virtual currencies adversely affects their property as a medium of exchange and renders a crowding...

Bitcoin is often labelled digital gold and many studies compare bitcoin and gold prices, returns and volatility. This paper digs deeper and compares the characteristics of bitcoin mining with gold mining to assess claims that bitcoin is digital gold. We identify twenty differences between gold...

This study shows that changes in bitcoin exchange reserves are negatively related to contemporaneous and future bitcoin returns, consistent with the hypothesis that the transfer of bitcoin on exchanges implies increased price pressure and vice versa. We further identify an asymmetry between...

It is a hybrid between fiat currency and commodity currency without intrinsic value and independent of any government or monetary authority. This paper analyses the question of whether Bitcoin is a medium of...

This paper analyzes high-frequency estimates of good and bad realized volatility of Bitcoin. We show that volatility asymmetry depends on the volatility regime and the forecast horizon. For one-day ahead forecasts, good volatility commands a stronger impact on future volatility than bad...
