HBAR experienced a significant decline of 11.5% on Tuesday, driven by substantial institutional selling. The token's price fell from $0.1426 to $0.1281, breaking the crucial $0.1350 support level. This drop was triggered by a massive sell-off of 250.3 million units at 07:00 GMT, nearly double the average 24-hour trading volume, which led to a cascade of stop-loss orders. The selling pressure continued throughout the session, with HBAR testing the $0.1277 zone as the market saw consecutive lower highs and increased trading volume. Despite ongoing network development efforts, institutional selling dominated the market, causing sharp volume spikes and a final drop to $0.1277 before activity stalled, indicating possible aggressive absorption or a technical halt.
