Recently, bitcoin price has been increased so much. The demand in bitcoin causes many transactions. If you send bitcoin with too low of a miners fee, your Bitcoin transaction may be pending! Normally, your transaction will be returned if after 72hours without any confirmations. How can you do in this case if you face that problem? You need to do a transaction accelerator to push your unconfirmed bitcoin transaction.

1. Define your Transaction ID. You can find your Transaction ID  with a format like "79a1d749adad267bdfd53d6fcc941fbc92ce5826114f37278c6dcaaf6d19be02” by searching the Bitcoin address for your transaction at [www.blockchain.info](http://www.blockchain.info).
2. Head over to  https://www.viabtc.com/tools/txaccelerator/ 
3. Input your Transaction ID --> retype Captcha and press Submit

You may see three cases below

**1. Submission are beyond limit. Please try later** This happens because **every hour only 100 transactions can be accepted.**

How to calculate reasonable fee. How to push unconfirmed transactions Note important information below

**IMPORTANT NOTE**

Because only 100 transaction accepted each hour, it runs out of limit super fast. So you need to put your transaction ID **within 30s OF THE FIRST MINUTE EACH HOUR**. For example, if you submit want to submit your transaction at 9AM you should put your transaction ID from 9h00m02s -> 9h00m30s. Again, this is very important to get accepted.

How to prevent pending situation?

- Don't send your coin from unconfirmed transaction
- Don't send coin with insufficient fee. You can check bitcoin suggested fees at [https://bitcoinfees.21.co/](https://bitcoinfees.21.co/)
