Corporate Bitcoin holdings, now exceeding 4% of the total supply, could trigger a bear market, according to BeInCrypto. Companies like Strategy (formerly MicroStrategy) are at the forefront of this trend, using Bitcoin as a treasury asset. However, the report warns that distressed firms might be forced to sell their holdings during downturns, potentially causing a 'reflexive death spiral' that exacerbates market declines. This scenario could also attract increased regulatory scrutiny.
