This paper provides an empirical analysis of the distributional properties and statistical regularities of virtual, intra-virtual and traditional currency exchange rates. To perform the analysis, the most relevant virtual, intra-virtual and foreign currency exchange rates between October and December are examined. The analysis shows that, in spite of their differing mode of formation, daily log-returns of all currency types share tent-shaped empirical densities, one of the characteristics of a Laplace distribution at semi-log scale.

Mysql – Efficient schema to handle time interval queries on a huge table
It remains to be seen how the tech evolves, but meanwhile we can do some basic technical analysis on what's fuelling the growth and to see if it's sustainable. In this recipe, we'll analyze bitcoin, ethereum and other cryptocoin performances using intermediate to advanced SQL:. Disclaimer: The purpose here is to teach SQL and timeseries data analysis, and not be a deep-dive technical post on cryptocoins. And it's most certainly not financial advice.

Bitcoin provides its users with transaction-processing services which are similar to those of traditional payment systems. We find that this decentralized design protects users from monopoly pricing. Competition among service providers within the platform and free entry imply no entity can profitably affect the level of fees paid by users. Instead, a market for transaction-processing determines the fees users pay to gain priority and avoid transaction-processing delays. The Appendix describes and explains the main attributes of Bitcoin and the underlying blockchain technology. The recipients of this revenue—payment-processing firms—enjoy network effects and economies of scale, and therefore limited competition and barriers to entry Rosenbaum et al. Multiple lawsuits against payment-processing firms accuse them of abusing their market power and harming welfare.
