Abstract
This study was conducted to identify the
existence of the phenomenon of Dragon Kings (DKs) in five notable
cryptocurrencies, namely Bitcoin, Dogecoin, Ethereum, Litecoin and Ripple. DKs
are meaningful extreme outliers that occasionally fall outside the Pareto or
power-law distribution. These examples have been statistically identified as
extreme of extreme returns that occur more frequently than the power law
distribution predicts. The study uses the Pareto distribution, usually
associated with extreme data, to examine the upper and lower tails of returns.
The result shows that the upper and lower tails of the returns of all the
cryptocurrencies studied prove the existence of the Dragon Kings mechanism.
Contrary to expectations, Bitcoin has seen the most unpreditable of extreme
returns compared to other cryptocurrencies. This characteristic causes Bitcoin
notably challenging to forecast. The results of this study are crucial for investors to evaluate and
understand the Dragon King events, which represent returns that are
exceptionally extreme even among other extreme values (super-extreme) observed
in these financial assets.
Keywords: Cryptocurrency; Dragon Kings; extreme outliers
Abstrak
Kajian ini dijalankan untuk mengenal pasti kewujudan fenomena Raja Naga (DK) dalam lima mata wang kripto yang terkenal, iaitu Bitcoin,
Dogecoin, Ethereum, Litecoin dan Ripple. DK adalah pencilan ekstrem yang bermakna yang adakalanya jatuh di luar taburan Pareto atau kuasa. Contoh ini telah dikenal pasti secara statistik sebagai pulangan ekstrem yang berlaku lebih kerap daripada yang diramalkan oleh taburan kuasa. Kajian ini menggunakan taburan Pareto yang biasanya dikaitkan dengan data ekstrem untuk meneliti ekor atas dan bawah pulangan. Keputusan menunjukkan bahawa ekor atas dan bawah pulangan semua mata wang kripto yang dikaji membuktikan kewujudan mekanisme Raja Naga. Bertentangan dengan jangkaan, Bitcoin telah melihat pulangan ekstrem yang paling tidak dapat diramalkan berbanding dengan mata wang kripto yang lain. Ciri ini menyebabkan Bitcoin sangat sukar untuk diramalkan. Keputusan kajian ini adalah kritikal bagi pelabur untuk menilai dan memahami secara ekstrem terhadap pulangan ekstrem yang boleh berlaku dalam aset kewangan ini.
