Institutional investors have injected $302 million into the Bitcoin market, signaling renewed interest amid bullish sentiment. This influx comes as weekly outflows from exchanges and a low exchange whale ratio of 0.43 indicate that large holders and long-term investors are retaining their assets, tightening the available supply. Analysts suggest that this institutional activity, rather than retail trading, is driving Bitcoin's recent surge past $125,000, potentially supporting further price increases.
