99bitcoins review of literature
Although it seems relatively obvious that bubbles exist within the cryptocurrency market, in finance and economics, the possibility of financial bubbles is often excluded based on market efficiency rationalization, 4 which assume an unpredictable market price, for instance following a kind of geometrical random walk e. By sharp contrast, Didier Sornette and co-workers claim that bubbles exist and are ubiquitous. Moreover, they can be accurately described by a nonlinear trend called the Log-Periodic Power Law Singularity LPPLS model, potentially with highly persistent, but ultimately mean-reverting, errors.
The LPPLS model combines two well-documented empirical and phenomenological features of bubbles see [ 28 ] for a recent review : 1 the price exhibits a transient faster-than-exponential growth i. Such log-periodic fluctuations are ubiquitous in complex systems with a hierarchical structure and also appear spontaneously as a result of the interplay between i inertia, ii nonlinear positive and iii nonlinear negative feedback loops [ 32 ]. The model thus characterizes a process in which, as speculative frenzy intensifies, the bubble matures towards its endogenous critical point, and becomes increasingly unstable, such that any small disturbance can trigger a crash.
This has been further formalized in the so-called JLS model where the rate of return accelerates towards a singularity, compensated by the growing crash hazard rate [ 30 , 33 ], providing a generalized return—risk relationship. We emphasize that one should not focus on the instantaneous and rather unpredictable trigger itself, but monitor the increasingly unstable state of the bubbly market, and prepare for a correction. Finding evidence of positive feedbacks between price and online activity, potential for bubble formation was suggested.
However, the model focuses on moderate short-term effects, and integrates to produce a linear price trend—neither producing large bubbles, nor a justified fundamental value. Notably, in [ 36 ] it was claimed that the fundamental value of Bitcoin is zero. Further, explosive unit-roots have been detected in the Bitcoin value e. These tests may identify bubbles—insofar as bubbles can be explained by a consistent mildly explosive unit-root, while perhaps also allowing for a log-linear trend—but are not specific [ 40 ], and have limited descriptive and predictive power.
When both measures coincide, this provides a convincing indication of a bubble and impending correction. If, in hindsight, such signals are followed by a correction similar to that suggested, they provide compelling evidence that a bubble and crash did indeed take place.
This paper is organized as follows. On this basis, we identify a current substantial but not unprecedented overvaluation in the price of Bitcoin. In the second part of the paper, we unearth a universal super-exponential bubble signature in four Bitcoin bubbles, which corresponds to the LPPLS model with a reasonable range of parameters. The LPPLS model is shown to provide advance warning, in particular with confidence intervals for the critical bursting time based on profile likelihood.
An LPPLS fitting algorithm is presented, allowing for selection of the bubble start time, and offering an interval for the crash time, in a probabilistically sound way. Regardless of the potential importance of stability in the cryptocurrency market, a few studies have examined if stablecoins are truly stable. With the regard to the stability of stablecoins, Hoang and Baur identify Bitcoin as a source of excess volatility in stablecoins and also provide evidence that stablecoins contribute to the excess volatility of Bitcoin.
In addition, Grobys find the spillover effects of Bitcoin volatility on stablecoins. We extend the scope of the studies of Hoang and Baur and Grobys and ask if there exists a volatility spillover among stablecoins. The connectedness in the cryptocurrency market has been extensively studied for traditional cryptocurrencies, but not for stablecoins, so our study attempts to fill this gap. The literature on the correlation among traditional cryptocurrencies largely agrees that Bitcoin is the center of the connectedness.
For example, Moratis examines the pairwise directional spillover shocks for the 30 largest cryptocurrencies including 1 stablecoin and finds that Bitcoin dominates others in the risk transmission process. In addition, by investigating the tail-risk interdependence among 23 cryptocurrencies, Xu et al.
By examining the return connectedness of seven largest traditional cryptocurrencies, Bouri et al. Ferreira et al. These previous studies focus only on traditional cryptocurrencies, the volatility spillover among stablecoins remains unexplained in the literature. The current study seeks to contribute to the literature by analyzing the relationship of the stabilities of the largest five stablecoins.
In this regard, we argue that signaling theory plays a significant role in explaining the interrelation between stablecoins. As cryptocurrency market and stablecoins are in their early stage of development, the tech-savvy in this market may create information asymmetry to investors for their trading decisions.
This is in line with the arguments from Philippi et al. In the context of stablecoins, we argue that the price movement of large-cap stablecoins can be interpreted as signals on trading opportunities for smaller-cap stablecoins by investors. Therefore, large-cap stablecoins tend to drive smaller ones. The findings are expected to show how larger stablecoin price changes influence the prices of lower market cap stable coins because stablecoins users can easily switch between different types of stablecoins in the cryptocurrency market.
The rest of the paper is organized as follows. Section 2 describes the data and the econometric model; Sect. According to Coinmarketcap, the price of any cryptoassets is a volume-weighted average of market pair prices in several exchanges such as Binance or Huobi.
