The global cryptocurrency market has seen a significant contraction, with total market capitalization dropping 30% to US$2.7 trillion, following new tariffs announced by US President Donald Trump. Bitcoin has shown relative stability, decreasing to US$78,500 while increasing its market dominance to nearly 60%, as investors shift towards more stable assets. This downturn highlights the vulnerability of altcoins, which have faced steeper declines, reflecting a growing preference for Bitcoin during periods of market uncertainty.
