Bitcoin's recent surge to an all-time high has prompted significant sell-offs by miners and whales, potentially indicating a local peak. On July 15, Bitcoin exchange inflows soared to 81,000 BTC, marking the highest single-day inflow since February. This surge was largely driven by transfers of 100 BTC and above, which increased from 13,000 BTC to 58,000 BTC, alongside miner outflows of 16,000 BTC, nearly all deposited directly into exchanges. Ethereum mirrored this trend with approximately 2 million ETH entering exchanges on July 16, the largest daily inflow since late February. These movements suggest that major holders are capitalizing on the price rally, possibly signaling a temporary market top.
