• US futures dropped and Bitcoin tumbled over 5% below $65,000 after the Supreme Court struck down most of Donald Trump's tariffs.
• Asian markets showed mixed reactions; Hong Kong's Hang Seng surged 2.2%, while South Korea's Kospi edged lower and Australia's S&P/ASX 200 shed 0.6%.
• Bitcoin has lost nearly half its value since its October 6 record high of $126,210.50, driven by investor pullbacks from speculative assets and regulatory concerns.
