Bitcoin is the most valuable and well-known cryptocurrency in the world. But this popularity has given way to a lot of traffic on the Bitcoin blockchain, which, in turn, has led to long transaction times. Because of this, Bitcoin transaction accelerators have become widely used. But what is a Bitcoin transaction accelerator, and which is best for you?

What Is a Bitcoin Transaction Accelerator?

Bitcoin transaction accelerators are websites you can use to hopefully process a Bitcoin transaction faster. Within Bitcoin's blockchain network, it's up to miners to verify transactions and maintain the security of the ecosystem. When a transaction is conducted, it is broadcast for miners to pick up and process.

However, miners don't have to confirm any transaction immediately. Rather, miners prioritize transactions with the highest fees, as they are paid in transaction fees along with mining rewards.

The transaction verification process consists of at least three conformations. The Bitcoin blockchain itself is already overrun with a long queue of pending transactions in the mempool, where transactions wait for processing. So, if you're conducting a low-fee transaction and the blockchain is particularly busy, you may be left waiting quite a while to receive full confirmation.

This is where Bitcoin transaction accelerators come in. Using an accelerator, you're essentially rebroadcasting your transaction to increase the chance of a miner picking it up. Bitcoin miners run accelerator sites, which are either free or paid. Paid accelerators will prioritize your transaction, while free accelerators won't give it as much importance. Either way, the process involves reminding the miners that your transaction is yet to be finalized.

The Best Bitcoin Accelerators

Let's get into the best Bitcoin transaction accelerators you can try.

1. BitAccelerate

BitAccelerate is a popular Bitcoin transaction accelerator that is entirely free to use. Using BitAccelerate is very simple, as shown in the screenshot above. All you need to do is enter your Transaction ID (TXID) into the provided box, and you'll have your transaction rebroadcast in the network to 10 separate nodes (or miners).

BitAccelerate allows you to rebroadcast the same transaction once every six hours until it is processed. You can also check your transaction confirmation status using BitAccelerate.

Because BitAccelerate is free, it's worth noting that your rebroadcast transaction may not be prioritized as highly as those rebroadcast using a fee. Again, miners are looking to make a profit, so it's important that they prioritize paid rebroadcasts so that users continue to use the paid service for quicker confirmations.

But this doesn't mean BitAccelerate is useless. If you want to try and accelerate your transaction without forking out cash, then this website is certainly worth a try.

2. ViaBTC

The ViaBTC platform offers a range of services, including mining pools, an exchange, and a Bitcoin transaction accelerator. ViaBTC's transaction accelerator is super simple and can be used either free of charge or for a fee.

ViaBTC's free accelerator rebroadcasts your transaction, which must be no bigger than 0.5KB in size. You can submit up to 100 transactions for free every hour. With ViaBTC's paid accelerator, there is no size limit, and all cooperative mining pools are notified of your pending transaction, which will then be prioritized for confirmation. You can pay for this service using Bitcoin, Bitcoin Cash, or Litecoin.

But ViaBTC has warned users that its accelerator will not always succeed. This could be due to a number of reasons, such as a transaction that is too large, a fee that is too low, or a previously unconfirmed transaction. So, follow ViaBTC's rules carefully before submitting a transaction to accelerate.

3. BTC Nitro

BTC Nitro is another transaction accelerator that offers both a free and paid service. Using BTC Nitro's free service, you can confirm your transaction by rebroadcasting it within the network to both public and private nodes. This is not a guaranteed process and is best for transactions that are stuck or have been dropped from the mempool. Like ViaBTC, you can rebroadcast your transaction free of charge once every six hours.

On the other hand, you can use BTC Nitro's paid service, which prioritizes your transaction and enters it into a mining pool. This will automatically add your transaction to the next block for quicker confirmation.

BTC Nitro guarantees that, via their paid service, your transaction will be finalized in 24 hours at most, or you will be refunded. Each accelerated transaction costs $25, which can be paid for in Bitcoin. Because this is by no means a small fee, you could always try rebroadcasting your transaction via the free service first.

Speed Up Your Bitcoin Transactions!

As the Bitcoin network becomes more popular, super speedy transactions are becoming a rarity, with some users waiting multiple hours, or even days, for confirmation. This is why Bitcoin transaction accelerators are useful. So, if you think you're dealing with a stuck transaction, check out one of the accelerators above to give it a boost.
