Cathie Wood's Ark Invest predicts a potential over 3,000% rally for Bitcoin in the next 12 months following the recent halving event, which reduced Bitcoin's supply growth rate to below that of gold. The halving, a feature of Bitcoin's design to ensure scarcity, has historically been followed by bull market runs. Despite a recent lackluster sentiment post-halving, Ark's analysis suggests Bitcoin could become a less inflationary asset than gold, potentially influencing its value positively.
