Bitcoin rebounds toward $84K as Korean tech stocks decline amid AI and China concerns

Bitcoin (BTC) rebounded toward $84,000 on Tuesday, rising more than 2.5% to $83,944 on Bitstamp, while South Korea's KOSPI Composite Index extended its weekly losses to 7.4%, falling below its 200-day moving average for the first time since late July. Semiconductor stocks, including SK Hynix, fell more than 10%, driven by investor nerves over AI and Chinese competition; foreign investors sold around 173 trillion won ($129 billion) worth of SK Hynix and Samsung shares since the start of 2026. Bitcoin's relative strength occurred despite $451 million in net outflows from US spot Bitcoin ETFs in October.
