No clear reason emerged for the fall in prices. The first cryptocurrency plunged this weekend, according to different observers by a failure of Chinese power plants, a harsher tone of the American regulator or simply by the breathlessness of a market outperforming for months.

The leader of cryptocurrencies saw its price fall on Sunday to $ 51,708, 20% below the all-time high reached Wednesday at $ 64,870. Giles Coghlan, an analyst at HYCM, explains that the causes of this plunge range from power cuts in China to the market's slowdown after coinbase's IPO, as well as a possible hardening of the position of the US authorities.
Neil Wilson, an analyst at Markets.com believes that much of the decline can also be attributed to the speculation that surrounded Coinbase's IPO, and which is evaporating.
The arrival on Wall Street of one of the largest exchanges had led the cryptocurrency to its all-time high on Wednesday.
