Bitcoin users frequently encounter stuck transactions due to network congestion and low transaction fees. This issue has led to the rise of Bitcoin transaction accelerators, services designed to speed up confirmations by rebroadcasting transactions to miners. While some are highly effective, others charge excessive fees or fail to deliver results.In this guide, we’ll explore the top 5 Bitcoin transaction accelerators in 2025, comparing their features, pricing, and reliability to help you find the best option.
1. Fujn BTC Accelerator – The Most Reliable & Free BTC Accelerator
When it comes to fast and efficient Bitcoin acceleration, Fujn BTC Accelerator stands out as the best choice in 2025. Unlike other services, Fujn works with multiple mining pools, ensuring a higher success rate for transaction confirmations.
Key Features:
- Free & Paid Acceleration Options – Users can opt for free acceleration or priority service for urgent transactions.
- No Registration Required – Just enter your TXID, and the system automatically rebroadcasts your transaction.
- Backed by Large Mining Pools – Fujn partners with major mining pools to improve confirmation success rates.
- User-Friendly Interface – Simple, easy-to-use platform for all Bitcoin users.
Fujn BTC Accelerator provides a fast, free, and reliable way to ensure your Bitcoin transactions don’t remain stuck in the mempool for extended periods.
2. ViaBTC – Expensive but Trusted BTC Accelerator
ViaBTC is another well-known BTC accelerator, but it comes with a high price tag. While the service is reliable, it primarily caters to users willing to pay a premium fee to speed up their transactions.
Key Features:
- Offers Both Free & Paid Acceleration – Free service has limited availability, while paid acceleration guarantees priority confirmation.
- Single Mining Pool Dependency – Unlike Fujn, ViaBTC relies on a single mining pool, reducing success rates.
- High Fees for Priority Acceleration – Users must pay extra for faster processing.
Despite its high costs, ViaBTC remains a viable option for those willing to pay for acceleration. However, it lacks the broad mining pool integration that makes Fujn a better choice.
3. BTC Accelerate – A Free Alternative for Transaction Speed Boost
BTC Accelerate is another free BTC accelerator offering users the ability to rebroadcast transactions without requiring any fees.
Key Features:
- Completely Free Acceleration – No payment is required to submit a TXID.
- Easy-to-Use Interface – Users can accelerate their transactions with minimal steps.
- Limited Pool Support – Unlike Fujn, BTC Accelerate has fewer mining pool connections.
While BTC Accelerate is useful for free acceleration, its effectiveness depends on network congestion, making it less reliable than Fujn.
4. BTC.com – Once Reliable, Now Discontinued
BTC.com was a well-known Bitcoin accelerator, but as of 2025, it has been discontinued. Previously, BTC.com offered users a way to speed up transactions through its mining pool connections.
Why Was BTC.com Discontinued?
- The service became less effective due to changing mining dynamics.
- Users reported lower success rates compared to other accelerators.
- The company shifted focus away from BTC acceleration.
Since BTC.com no longer operates as a BTC accelerator, users should explore alternatives like Fujn BTC Accelerator or ViaBTC.
5. ConfirmTX – A Scam BTC Accelerator
Unlike the other services listed, ConfirmTX has been flagged by users as a potential scam. Many reports suggest that ConfirmTX does not actually accelerate transactions and instead tricks users into paying non-refundable fees.
Warning Signs of ConfirmTX Scam:
- Users report transactions never being confirmed after payment.
- No real mining pool integration – Unlike Fujn and ViaBTC, ConfirmTX does not work with legitimate miners.
- Lack of transparency – No clear information about its success rate or technical infrastructure.
Due to these concerns, it is highly recommended to avoid ConfirmTX and use trusted BTC accelerators like Fujn instead.
