Bitcoin faces softer demand as only 4 wallets top 100K BTC and exchange balances rise

Bitcoin traded at $66,845 at the time of writing, up 0.42% over the past 24 hours, while price action stayed range-bound. On-chain and flow metrics suggest weaker demand as exchange withdrawals hit 908 addresses and large-holder accumulation appears to stall. In derivatives, funding was slightly positive at 0.0037% but Open Interest slipped 0.87% to $46.14 billion, pointing to cautious positioning.
