Bitcoin’s Mempool was nearly empty due to low network activity, leading to faster, cheaper transactions—but a surge could happen anytime.
Recent data shows a significant slowdown in Bitcoin network activity, resulting in a near-empty Mempool and transaction fees dropping to their lowest levels in nearly a year. This shift, observed around early February, 2025. Typically, Bitcoin’s Mempool holds thousands of pending transactions, but over the past few days, it has been unusually sparse, allowing users to send Bitcoin at significantly reduced fees. This phenomenon has left many wondering: Why was the Bitcoin Mempool nearly empty, and what does it mean for the network?
In this article, we’ll explore the reasons behind it, analyze the implications for Bitcoiners, and discuss whether this trend is likely to continue. But first, let’s understand what the Bitcoin Mempool is in the next section below.
(P.S. If you're already familiar with the Bitcoin Mempool, feel free to skip ahead to the next section.)
The Mempool (short for memory pool) is a waiting room for Bitcoin transactions. When you send Bitcoin, your transaction enters the Mempool, where it waits to be picked up by miners and confirmed in a block.
During periods of high demand for Bitcoin, the Bitcoin Mempool becomes congested, leading to higher fees and longer confirmation times. Conversely, when activity slows, the Mempool empties, resulting in faster confirmations and lower fees.

Bitcoin’s Mempool Nearly Empties for the 2nd Time in History – Why Fees Are Dropping
"For only the second time in history, Bitcoin’s Mempool is nearly empty."
This rare event has sparked discussions across the Bitcoin community. The Mempool—where pending Bitcoin transactions wait to be confirmed—is typically filled with thousands of unconfirmed transactions, sometimes leading to high fees and delays.
However, the recent Mempool clearance is a rare occurrence, with the last known instance happening years ago. Adding to the conversation, Bitcoin historian Pete Rizzo highlighted that “Bitcoin transaction fees have fallen to their lowest level in two years” making BTC transactions incredibly cheap.
1. The Lightning Network’s Growing Adoption:
The Lightning Network has become a major factor in reducing on-chain activity. With continuous innovations and integrations, spending Bitcoin has never been easier, making on-chain transactions less preferable due to the scalability and efficiency Lightning offers.
2. Increased Use of Layer 2 Solutions:
More users and businesses are leveraging Layer 2 solutions like the Lightning Network, significantly reducing the need for on-chain transactions. Since Lightning enables fast, low-cost payments without requiring block space, this shift has directly contributed to a less congested Mempool.
By settling transactions off-chain and only using the Bitcoin blockchain for opening and closing channels, Lightning reduces demand for block space, leading to lower fees and an emptier Mempool.
1. Low Network Activity
The primary cause of a near-empty Mempool is a reduction in transaction volume. With fewer people sending Bitcoin, there’s less competition for block space. This could be due to:
2. Extremely Low Fees
Transaction fees recently dropped to 1-1 sat/vB, a significant decrease compared to the 10–50 sat/vB observed during periods of high demand.
This suggests miners are not competing aggressively for block space, allowing users to send transactions at much lower costs. The reduced fees are directly linked to the drop in demand for block space.
3. Potential Miner Revenue Decline
Since transaction fees make up a portion of miners’ earnings, lower fees can lead to reduced revenue, making them more dependent on block rewards. This could have implications as Bitcoin’s halving approaches and block subsidies decrease.
The recent slowdown in Bitcoin network activity, including the near-emptying of the Mempool, presents several opportunities for Bitcoin users:
With fees at multi-year lows, now is an excellent time to move Bitcoin at minimal cost. The lower transaction volume means users can transact without worrying about high fees.
Transactions are being included in the next block almost instantly, eliminating long wait times. This makes Bitcoin transfers much quicker and more efficient.
Businesses and individuals can take advantage of this low-fee period to consolidate old UTXOs (unspent transaction outputs). By combining multiple small transactions into fewer, larger ones, users can reduce future transaction fees and improve wallet management. This also helps streamline transactions and makes more efficient use of the blockchain.
However, while these benefits are clear, it’s worth noting that low network activity isn’t always a positive sign and could indicate a temporary slowdown in adoption or economic activity within the Bitcoin network.
Bitcoin’s Mempool is highly dynamic, meaning the current period of low activity is unlikely to last forever. The network has experienced similar phases in the past, only to see transaction volume surge again due to various factors.
Potential triggers for increased activity include:
Bitcoin Bull Run
One major trigger that could lead to a spike in transactions is a Bitcoin bull run. When Bitcoin’s price rises significantly, market activity tends to increase as traders, investors, and institutions rush to buy, sell, or move their holdings. Historically, bull markets have led to congestion in the Mempool, driving up transaction fees as demand for block space grows.
Major Announcements:
Major announcements and News within the Bitcoin ecosystem can reignite transaction activity. News about institutional adoption, regulatory clarity, or key technological upgrades—such as advancements in Bitcoin scaling solutions—could lead to increased on-chain movement. For example, if a large financial institution announces Bitcoin integration, we might see a surge in transactions as users react to the news.
While the current low-fee environment provides an opportunity for cheap transactions, it is unlikely to be a permanent state. The Mempool could fill up again at any time, reinforcing Bitcoin’s cyclical nature.
With Bitcoin's transaction fees at their lowest, this is a rare opportunity to move your Bitcoin quickly and cheaply. But why stop at just sending Bitcoin? Start using it for everyday payments effortlessly and spend your Bitcoin on what matters most to you.
