BTC goes through largest accumulation wave since 2023 Hristina Vasileva | usagoldmines.com

BTC is going through another notable wave of accumulation. Exchange outflows and shifts to self-custodied wallets have returned to levels not seen since 2023. 

A shift in BTC sentiment put accumulation back on the radar. As BTC regained the $85,000 level and moved above its 365-day average, accumulation happened for both whales and retail. 

Moving BTC to self-custody wallets is also a response to growing geopolitical uncertainty. While BTC trades as a riskier Nasdaq proxy during boom times, it can also serve as a secure reserve, which still trades and settles 24/7. 

BTC self-custody comes in addition to ETF accumulation, and shows crypto natives are still not giving up on long-term storage, despite recent hacks and other threats. 

Binance shows peak BTC outflows

Another indicator of BTC accumulation is the sudden increase in outflows from Binance. Based on research by user @Darkfrost, BTC is showing signs of FOMO, as outflows reach levels not seen since 2023.

Binance is usually absorbing spare BTC during periods of bearish sentiment, while outflows signal a much lower selling pressure. Ahead of the withdrawal spree, Binance had around 705K BTC in its reserve. In the past week alone, the reserve shrank to around 689K BTC, based on Cryptoquant data.

Exchanges as a whole hold around 2.7M BTC, near all-time lows. The reserves did not expand even with recent miner deposits. BTC has been taken off exchanges not only for self-storage, but for additional safety, as exchanges are at a significant risk of hacks.

The recent Bitget hack may accelerate the rush to protect personal BTC holdings.  

In September, there was also a shift in the size of spot orders. Demand came from large whales, making relatively small but regular purchases. Orders ranged at around 798 BTC, starting off in early September and rising as the BTC price rally progressed.

General inflows to accumulation addresses also expanded in September, following a period of flat activity. 

For now, the accumulation has happened even without buying from treasury companies. Most treasury purchases have been frozen, while companies like Strategy and Metaplanet attempt to improve their balances and reserves. 

BTC shrimp and shark wallets gain activity

BTC accumulation is showing shrimp retail wallets may be making a return. Just as retail capitulated at the end of the previous bull cycle, buying is now returning once BTC has established a clear trend. 

In a single day, a total of 25,000 new shrimp wallets with under 1 BTC were created. For 2026 to date, the number of shrimp wallets has expanded by 4.64%.

Another cohort of active wallets is the shark-sized ones, holding 100 to 1,000 BTC. Those wallets also added BTC in the past month, expanding their total count by 4.62% in the year to date. 

According to holder records, all but the most recent BTC buyer wallets are increasing their balances. There were no signs of distribution during the BTC rally from lows of $59,000 to the recent local high at $87,000. The recent accumulation shows confidence in an ongoing BTC rally, as earlier buyers do not rush to distribute at this price range. 

Taking coins off exchanges also suggests another wave of confidence in the long-term BTC growth. For now, most of the BTC price pressure comes from the derivative market. BTC is in no danger of holder capitulation, as a large part of the supply has been redistributed to holders with long-term conviction. 

As a result, actual access to BTC may become even more scarce, while the leading crypto coin is used as collateral, a deep reserve, or simply a payment tool with still uncensored settlement.
