Grandpa, grandpa, tell me the one about Bitcoin being a safe haven: Evidence from the COVID-19 pandemics
Bitcoin being a safe haven asset is one of the traditional stories in the
cryptocurrency community. However, during its existence and relevant presence,
i.e. approximately since 2013, there has been no severe situation on the
financial markets globally to prove or disprove this story until the COVID-19
pandemics. We study the quantile correlations of Bitcoin and two benchmarks --
S\&P500 and VIX -- and we make comparison with gold as the traditional safe
haven asset. The Bitcoin safe haven story is shown and discussed to be
unsubstantiated and far-fetched, while gold comes out as a clear winner in this
contest.Comment: 8 pages, 4 figure
Blockchain Networks: Data Structures of Bitcoin, Monero, Zcash, Ethereum, Ripple and Iota
Blockchain is an emerging technology that has enabled many applications, from
cryptocurrencies to digital asset management and supply chains. Due to this
surge of popularity, analyzing the data stored on blockchains poses a new
critical challenge in data science.
To assist data scientists in various analytic tasks on a blockchain, in this
tutorial, we provide a systematic and comprehensive overview of the fundamental
elements of blockchain network models. We discuss how we can abstract
blockchain data as various types of networks and further use such associated
network abstractions to reap important insights on blockchains' structure,
organization, and functionality.Comment: 27 figures, 8 tables, 42 page
