Key Takeaways

  • Binance’s BTC reserves rose from ~616,000 to ~632,000 BTC in a month, with weekly average inflows tripling in under 10 days, a pattern analysts flag as a potential sell signal.
  • Bitcoin ETFs recorded more than $1.2 billion in outflows last week, reversing a near-full recovery from the November 2024 sell-off.
  • Whale wallets holding over 1,000 BTC added approximately 47,000 BTC over two weeks, marking the strongest large-holder accumulation signal since November 2024.

Binance recorded net positive Bitcoin deposits for nearly 10 consecutive days, pushing the exchange’s BTC reserves up by roughly 16,000 BTC over the past month, according to data shared by on-chain analyst Darkfost. The inflow surge coincided with more than $1.2 billion in Bitcoin ETF outflows last week, as Bitcoin traded at $77,101, down 12% year-to-date.

Binance’s Weekly Average BTC Deposits More Than Tripled in Under 10 Days

According to Darkfost’s data, Binance’s weekly average of Bitcoin inflows rose from 378 BTC on May 16 to 1,190 BTC by May 25, representing a more than threefold increase in less than 10 days. The single largest spike occurred on May 18, when more than 3,600 BTC reportedly flowed into the exchange in one day. 

Over the full month, Binance’s BTC reserves climbed from approximately 616,000 BTC on April 24 to around 632,000 BTC on May 25. Darkfost said rising exchange inflows are “often read as a potential sell signal.”
