CORRELATION-BASED NETWORK EXAMINATION OF CRYPTOCURRENCIES’ PRICE DYNAMICS DURING ECONOMIC DOWNTURNS This research first provides an overview on blockchain technology, consensus mechanisms, mining process, transaction fees, soft and hard forks, Initial Coin Offerings (ICOs), and coin burning. Then it analyses ten major cryptocurrencies in terms of market capitalization, exploring their use cases, similarities and differences and delving into the specific features that might affect their price formation mechanisms. The aim of this analysis is to identify what drives price changes of cryptocurrencies on a same exchange market but also in relation to their connections with traditional assets like commodities and financial indexes. Findings from the employment of correlation networks reveal that cryptocurrencies may exhibit strong interconnectedness, even more during periods of market turbulences, with some exceptions in terms of behaviours over time and with respect to the potential diversification opportunities provided to the investors. To this aim, the methodology involved the application of an enriched Vector Autoregressive model, incorporating a correlation network model based on partial correlations, to understand how contemporaneous contagion effects are transmitted on a digital exchange market and between crypto and traditional markets. Lastly, further analyses across different exchanges and time periods are proposed to provide additional insights, also highlighting the potential benefits of taking advantage of network models in other branches of studies about cryptocurrencies, thus offering valuable insights for investors.
CORRELATION-BASED NETWORK EXAMINATION OF CRYPTOCURRENCIES’ PRICE DYNAMICS DURING ECONOMIC DOWNTURNS Questa ricerca fornisce una panoramica sulla tecnologia blockchain, sui meccanismi di consenso, sul processo di mining, sulle transaction fees, sui soft e hard forks, sulle Initial Coin Offerings (ICO) e sul coin burning. In seguito, vengono analizzate le dieci principali criptovalute in termini di capitalizzazione di mercato, le loro applicazioni, somiglianze e differenze e approfondite le caratteristiche specifiche che potrebbero influenzare i loro meccanismi di formazione dei prezzi. L'obiettivo di questa analisi è identificare cosa determini le variazioni di prezzo delle criptovalute su uno stesso exchange, anche in relazione alle loro interdipendenze con asset tradizionali come le materie prime e gli indici finanziari. I risultati dell'impiego dei correlation networks rivelano che le criptovalute possono presentare una forte interconnessione, ancor più durante i periodi di crisi, con alcune eccezioni rispetto ai periodi considerati e alle potenziali opportunità di diversificazione offerte agli investitori. A tal fine, la metodologia include l'applicazione di un vector autoregressive model che incorpora un correlation network basato su correlazioni parziali, per comprendere come gli effetti di contagio contemporanei dei prezzi si trasmettano su un exchange e tra mercati di criptovalute e tradizionali. Infine, vengono proposte analisi aggiuntive su diversi exchanges e periodi di tempo per fornire ulteriori approfondimenti, evidenziando anche i potenziali vantaggi dell’impiego dei correlation networks in altre branche di studio sulle criptovalute, offrendo vantaggi agli investitori.

Abstract
CORRELATION-BASED NETWORK EXAMINATION OF CRYPTOCURRENCIES’ PRICE DYNAMICS DURING ECONOMIC DOWNTURNS This research first provides an overview on blockchain technology, consensus mechanisms, mining process, transaction fees, soft and hard forks, Initial Coin Offerings (ICOs), and coin burning. Then it analyses ten major cryptocurrencies in terms of market capitalization, exploring their use cases, similarities and differences and delving into the specific features that might affect their price formation mechanisms. The aim of this analysis is to identify what drives price changes of cryptocurrencies on a same exchange market but also in relation to their connections with traditional assets like commodities and financial indexes. Findings from the employment of correlation networks reveal that cryptocurrencies may exhibit strong interconnectedness, even more during periods of market turbulences, with some exceptions in terms of behaviours over time and with respect to the potential diversification opportunities provided to the investors. To this aim, the methodology involved the application of an enriched Vector Autoregressive model, incorporating a correlation network model based on partial correlations, to understand how contemporaneous contagion effects are transmitted on a digital exchange market and between crypto and traditional markets. Lastly, further analyses across different exchanges and time periods are proposed to provide additional insights, also highlighting the potential benefits of taking advantage of network models in other branches of studies about cryptocurrencies, thus offering valuable insights for investors.È consentito all'utente scaricare e condividere i documenti disponibili a testo pieno in UNITESI UNIPV nel rispetto della licenza Creative Commons del tipo CC BY NC ND.
