Bitcoin whale accumulation jumped sharply over the weekend, with the 1K-10K BTC holder cohort adding 27,652 BTC in a single Sunday session. That is over $2 billion in a single day. The timing is not random.
On-chain analytics platform Santiment flagged the move on X, noting that wallets in the 1,000 to 10,000 BTC range now hold over 4.25 million BTC. According to Santiment (@santimentfeed) on X:
“Whales holding between 1K-10K Bitcoin now hold over 4.25M $BTC (21.3% of the supply). This is the most coins they’ve held since mid-February. The 27,652 BTC added Sunday equates to just over $2B in accumulation.”
That 21.3% supply share is the highest concentration this cohort has held in roughly two months. Bitcoin rebounded to $72.6K the same day Santiment posted the data.
Whale Buying Meets a Technical Crossroads
The accumulation did not happen in a vacuum. Technical analyst @CW8900 on X pointed out that BTC is now pressing against the upper boundary of a bearish pattern that has been in play for weeks. A confirmed break above that line, in their view, signals the start of a new uptrend.
“BTC is getting closer to the upper line of the bearish pattern. The biggest correction of this cycle is coming to an end. A breakout of the upper line marks the beginning of another uptrend. Additionally, a golden cross on the sub-indicators is also getting very close.”
Two signals converging at once. The on-chain data showing supply concentration, and a chart pattern that has not yet broken but is close. That combination is what makes this moment different from prior weeks.
The Supply Math Behind the Move
4.25 million BTC held by a single whale cohort is roughly $308 billion at current prices. Not a small figure. The mid-tier whale category, addresses holding between one thousand and ten thousand coins, has historically acted as a leading indicator before major price moves. They are large enough to move supply but not large enough to be exchanges or ETF custodians, which makes their behavior harder to dismiss as operational.
The 27,652 BTC added in one session is a meaningful single-day number. For context, the entire Bitcoin network produces around 450 new coins per day post-halving. Sunday’s buy absorbed what would take roughly 61 days of new supply to produce. That supply is now off the market.
Golden Cross Timing
The sub-indicator golden cross flagged by @CW8900 has not yet formed but is described as very close. A golden cross occurs when a shorter-period moving average crosses above a longer one, a signal some technical traders read as a shift in momentum. The fact that it is forming on sub-indicators rather than the primary chart suggests early-stage momentum building, not confirmation of a full trend reversal.
That distinction matters. The pattern breakout is not confirmed. The golden cross is not confirmed. But both are closer than they were a week ago, and the whale accumulation data arrived the same weekend both signals moved into proximity.
Traders watching BTC for a sustained recovery will likely track whether the coin can close above the bearish pattern’s upper line on a daily candle. Until that happens, the on-chain demand signal and the technical setup remain two separate pieces pointing in the same direction.
