Bitcoin Miners Are Selling More BTC — A New Supply Test for the Market

Bitcoin miners are back in focus after fresh signs that some are selling more BTC to raise money. The moves come as bitcoin trades in a choppy range and market liquidity looks thin, which can make even routine selling feel bigger than it is.

A supply shock is building in crypto right now… and almost nobody sees it coming.

Here's what's happening behind the scenes…

The GENIUS Act gave banks the green light to issue crypto backed by U.S. dollars. The Trump family's DeFi platform just applied for a federal bank charter to custody and issue their $3.3 billion stablecoin. 

And institutional capital that's been waiting on the sidelines is about to get its regulated on-ramp.

When that money hits the crypto ecosystem, it won't trickle in. It will flood.

And there's one coin positioned directly in the path of that flood.

It's infrastructure for an entire DeFi ecosystem… the kind of platform institutions will want to use as adoption accelerates. Think early Uniswap, but backed by Trump-era policy tailwinds.

Volume is surging. Smart money is accumulating. Market cap is still under $2 billion. And prices across the market are sitting at extreme fear lows not seen since 2022.

Low price. Massive catalyst. Tiny window.

One of the clearest signals this week came from Bitdeer Technologies, a major mining company. In its latest weekly update, Bitdeer said its corporate bitcoin “pure holdings” fell to 0 BTC. It reported producing 189.8 BTC during the week and selling all of it, plus selling 943.1 BTC from its treasury.

That kind of sale matters because many public miners have tried to hold at least part of their bitcoin as a reserve during bull markets. When a large miner goes to zero, it tells investors that cash needs are winning over the “hold BTC” strategy.

This is not the only data point. Earlier in February, on-chain trackers flagged unusually large miner-related transfers during volatile sessions. One report cited 28,605 BTC leaving miner-linked wallets on Feb. 5, and another 20,169 BTC on Feb. 6, based on CryptoQuant data cited in the piece. Not all transfers equal selling, but big spikes often raise concern about supply hitting the market.

At the same time, Glassnode data shows miners still hold a large stash overall—about 1,779,649 BTC as of Feb. 23, 2026—so even a few big sellers can change sentiment without draining the whole bucket.

Miners are a “natural seller” in bitcoin. They have steady bills—power, machines, and hosting—and they earn BTC on a fixed schedule. When prices fall or costs rise, they often sell more to cover expenses.

The timing matters too. CoinDesk reported bitcoin dropped sharply overnight before rebounding, and said thin liquidity amplified moves during that session. In simple terms: when there are fewer buyers and sellers near the current price, a market order can push price around more than usual.

That is why miner selling can feel like a “supply test.” If miners (and other large holders) sell into a market with weak depth, price can slip faster, triggering liquidations and more forced selling. Even if miners are not the main driver, they can add fuel during fragile moments.

There is also a second layer: some miners are shifting strategy. A number of miners have been talking more about AI and data center expansion. If firms want to fund new builds, pay down debt, or shore up working capital, selling BTC becomes a quick source of liquidity—especially if equity or debt markets are less friendly.

Miner selling can create cleaner entry points when the broader trend is still intact. If miners dump into weakness, price often overshoots to the downside. That can attract longer-term buyers who were waiting for better levels. It also helps “reset” leverage, because fast drops tend to flush out overextended traders.

It can also be a sign the market is maturing. Many miners used to rely on constant selling with little treasury strategy. Over the last few years, more public miners built balance sheet playbooks: hold some BTC, hedge some exposure, and sell when they need cash. When a miner chooses to sell more, it can be an intentional capital decision, not just panic. That gives investors clearer signals about which operators are disciplined and which are stressed.

At the same time, the biggest risk is simple: extra supply hitting a thin market. If liquidity is weak, even moderate miner selling can push bitcoin lower and trigger stop-losses and liquidations. That can turn a normal pullback into a sharper slide, especially during U.S. trading hours when macro headlines and risk assets can move together.

Another risk is that on-chain “miner outflow” headlines can move faster than the facts. Wallet transfers do not always equal spot selling. Coins can move to custodians, collateral accounts, or OTC desks without directly pressuring exchange order books. But traders often react first, so sentiment can sour even if the real market impact is smaller than the on-chain charts suggest.

Finally, miner selling can hint at financial strain in parts of the mining industry. If more firms are forced to sell into dips to cover power bills or debt, they may cut back on expansion or sell equipment. That can ripple into mining stocks and the broader crypto equity complex, especially if investors start pricing in higher bankruptcy or dilution risk.

For investors, the key is not to treat “miners are selling” as a single on/off switch. Watch the trend.

Three practical things to monitor next:

Miner holdings as a backdrop. Miners still control a meaningful pool of BTC, so even small percentage changes can matter at the margin.

Miner selling is not new, but it matters more when liquidity is thin and prices are jumpy. Bitdeer’s move to sell its full treasury is a loud data point that some miners are choosing safety and funding needs over holding bitcoin.

If miner sales spread, bitcoin could face a tougher climb in the near term. If the market absorbs the supply without breaking down, it would be a sign that demand is stronger than the headlines suggest.
