Businesses Are Absorbing Bitcoin at 4x the Rate It Is Mined, According to River’s Research
River’s new flow map suggests companies absorb around 1,755 BTC per day versus approximately 450 mined, with funds and ETFs adding more demand.

River says companies are taking in far more bitcoin each day than miners create.
The U.S.-based bitcoin financial services firm, which runs brokerage and mining operations and publishes research, released a Sankey-style flow infographic dated Aug. 25 in a post on X. In this layout, outflows are shown on the left, inflows on the right, and the thickness of each line represents the size of the net daily movement.
River defines “businesses” broadly. The category combines bitcoin treasury companies — firms such as Strategy that publicly hold BTC — with conventional companies that keep bitcoin on their balance sheets. Based on public filings, custodial address tagging and its own heuristics, River estimates that about 1,755 BTC per day flow into business-controlled wallets.
By comparison, River calculates new miner supply at about 450 BTC per day in 2025. That figure reflects the April 2024 halving, which cut the block subsidy to 3.125 BTC per block.
With bitcoin blocks averaging one every 10 minutes — about 144 per day — the result is roughly 450 BTC in new issuance daily, though the exact number fluctuates slightly as block times vary.
That math is the basis for River’s claim that companies are absorbing bitcoin at nearly four times the rate it is mined.
The infographic shows other large institutional inflows as well.
Funds and ETFs account for about 1,430 BTC/day in net inflows, which further boosts total absorption compared with new issuance. Smaller streams go to “other” entities (about 411 BTC/day) and governments (about 39 BTC/day).
River also records a small but steady flow into “lost bitcoin” (about 14 BTC/day), representing coins that the firm judges to be permanently inaccessible, such as through key loss.
On the other side of the ledger, individuals appear as the largest net outflow at about –3,196 BTC/day. River stresses that this does not necessarily mean retail investors are dumping coins. Rather, it reflects bitcoin moving from addresses the firm classifies as individual-held into those it tags as institutional.
River says the takeaway is simple: when inflows to businesses and funds exceed new issuance from miners, available supply tightens. Still, the firm cautions that the infographic should be read carefully.
First, the figures are estimates, not an exact census of the blockchain.
River relies on a mix of wallet tagging, public disclosures and external databases, which may miss some holdings or misclassify certain addresses. Second, net inflows do not always equal direct spot buying. A business wallet showing +1,755 BTC per day could reflect OTC transactions, custodial transfers or treasury reshuffling, not just exchange purchases.
For readers unfamiliar with flow diagrams, the point is this: the lines show where coins are ending up on balance, not every trade or transfer in the system. If more coins consistently end up in business, fund and government wallets than miners are producing, River argues that institutions are tightening supply at the margin.
River’s snapshot is not a price forecast, but it illustrates how ownership patterns may be shifting. If businesses and funds continue to absorb more than miners produce, the firm argues, institutions could play a larger role in shaping bitcoin’s supply dynamics.

Crypto Charts Look ‘So Broken and Bearish They’re Bullish’ Ahead of Fed Meeting, Says Analyst
Alex Krüger says recent liquidations and scary charts could set up a bullish rebound, though conviction trends may wait until after the Fed’s Sept. 17 decision.
What to know:
- Analyst Alex Krüger says extreme bearish-looking charts can flip bullish once forced selling clears leverage.
- He sees little trend until after the Fed’s next rate decision on Sept. 17, following the conclusion of the two-day FOMC meeting.
- Krüger insists the cycle isn’t over and sees SOL as a possible outlier due to new decentralized treasuries building on the chain.
