Bitcoin remains the world’s most widely used cryptocurrency, but even after more than a decade of adoption, users still face a common frustration: stuck transactions. When network congestion spikes or transaction fees are set too low, your BTC transfer can linger in the mempool for hours—or even days. This delay isn't just inconvenient; it can disrupt time-sensitive payments and trading strategies.
That’s where Bitcoin transaction accelerators come in. These services help push pending transactions into the next available blocks by rebroadcasting them to mining pools or leveraging fee-bumping mechanisms. With 2025 bringing renewed volatility and increased on-chain activity, choosing the right accelerator has never been more critical.
In this guide, we’ll break down the top 5 Bitcoin transaction accelerators in 2025, evaluating each based on reliability, cost, ease of use, and integration with active mining networks. Whether you're a casual user or a frequent trader, this overview will help you avoid delays and get your transactions confirmed faster.
Fujn BTC Accelerator – The Most Reliable & Free Option

Fujn delivers a rare combination: free service, high success rate, and strong infrastructure. It’s particularly effective for transactions stuck due to low fees, offering a realistic path to confirmation without overpaying.
ViaBTC – Trusted but Costly Acceleration Service
ViaBTC is a well-established name in the Bitcoin ecosystem, known primarily as a mining pool operator. Its transaction accelerator leverages internal mining resources to prioritize user transactions—but at a steep price.
While reliable, ViaBTC’s model reflects a premium service designed for users who value speed over cost efficiency.
Key Features:
- Free Tier with Limited Availability: Occasional free slots exist, but most users must pay for acceleration.
- Single Mining Pool Dependency: Unlike Fujn, ViaBTC only uses its own mining power, which limits reach across the broader network.
- High Priority Fees: Users often pay significantly more compared to alternative solutions for guaranteed inclusion.
Despite its effectiveness, ViaBTC’s lack of multi-pool integration reduces overall reliability during network peaks. However, if you're willing to pay extra for a reputable provider, it remains a viable short-term solution.
BTC Accelerate – A Simple Free Alternative
For users seeking zero-cost solutions, BTC Accelerate offers a no-frills option. The service allows anyone to submit a TXID for rebroadcasting without charging any fees.
It’s straightforward and accessible—but comes with notable limitations.
Key Features:
- Completely Free to Use: No payment or registration required.
- User-Friendly Design: Minimal steps needed to initiate acceleration.
- Limited Mining Support: Only connects to a small number of pools, reducing effectiveness during congestion.
While BTC Accelerate can work under ideal conditions, its success rate fluctuates heavily based on current network load. As such, it’s best suited for non-urgent transactions where patience is an option.
BTC.com – Former Leader Now Discontinued
BTC.com was once a go-to platform for transaction acceleration, backed by one of the largest mining pools in the industry. However, as of 2025, the service has been officially discontinued.
Why BTC.com Shut Down Acceleration Services:
- Shifting business focus away from consumer tools toward enterprise blockchain solutions.
- Declining effectiveness due to evolving mining economics and competition.
- Falling user trust amid reports of inconsistent results.
With BTC.com no longer operational as an accelerator, users must turn to active alternatives like Fujn or ViaBTC to resolve stuck transactions.
ConfirmTX – Widely Flagged as a Scam
Among the services claiming to accelerate Bitcoin transactions, ConfirmTX stands out—but for all the wrong reasons.
Multiple user reports and community warnings label ConfirmTX as a potential scam, with consistent allegations that payments do not result in actual transaction confirmations.
Red Flags to Watch For:
- Users report paying fees but seeing no improvement in transaction status.
- No verifiable integration with real mining pools.
- Lack of transparency around operations, success metrics, or technical details.
Given these serious concerns, it is strongly advised to avoid ConfirmTX entirely and stick with trusted providers that have proven track records.
Frequently Asked Questions (FAQ)
Q: What causes a Bitcoin transaction to get stuck?
A: Transactions often stall when the attached fee is too low compared to current network demand. Miners prioritize higher-paying transactions, leaving low-fee ones waiting in the mempool.
Q: How do Bitcoin transaction accelerators work?
A: Most accelerators rebroadcast your transaction to multiple nodes and mining pools, increasing visibility. Some also offer Replace-by-Fee (RBF) or Child-Pays-for-Parent (CPFP) tools to boost priority.
Q: Are free BTC accelerators reliable?
A: It depends. Services like Fujn combine free access with real mining partnerships, making them trustworthy. Others with limited infrastructure may fail under congestion.
Q: Can I lose my funds using an accelerator?
A: No—your funds aren’t at risk of being stolen through legitimate accelerators. However, scams like ConfirmTX may take your payment without delivering service.

A: Yes. Use wallets that suggest dynamic fees based on real-time network data. You can also manually increase fees if you anticipate congestion.
Q: Do all accelerators support RBF or CPFP?
A: Not all. Most third-party accelerators focus on rebroadcasting. For advanced options like RBF or CPFP, consider using native features within wallets like Electrum or Bitcoin Core.
Final Verdict: Which Bitcoin Accelerator Should You Use?
After evaluating speed, cost, reliability, and technical backing, Fujn BTC Accelerator emerges as the best overall choice in 2025. It uniquely combines free access, multi-pool integration, and a clean interface—making it ideal for both new and experienced users.
While ViaBTC offers reliability at a cost, and BTC Accelerate provides basic free service, neither matches Fujn’s balance of performance and accessibility. Meanwhile, outdated platforms like BTC.com are no longer viable, and services like ConfirmTX should be avoided altogether due to fraud risks.
👉 Stay ahead of network delays with smart transaction management tools.
Ultimately, the key to avoiding prolonged confirmation times lies not just in accelerators—but in proactive fee management and using platforms that adapt to real-time blockchain conditions. As Bitcoin continues evolving in 2025 and beyond, staying informed ensures your transactions stay fast, secure, and successful.
