Bitcoin transaction ("mining") fees

Adrian (Melbourne) -

Transaction fees

When transferring funds from your CoinJar to an external bitcoin address, a bitcoin transaction fee is required in order for your transfer to be completed promptly. Transaction fees provide bitcoin “miners” incentive to continue processing bitcoin transactions, and including an appropriate fee to your bitcoin transfer will directly influence the time it takes for that amount to be confirmed on the blockchain.


Internal CoinJar transfers

Because payments made from one CoinJar to another are not sent via the blockchain, a transaction fee isn’t required in order to process the transfer. Internal CoinJar transfers are completed instantly.


How CoinJar handles transaction fees

When you make a new outgoing bitcoin transfer with CoinJar, a 0.0005 bitcoin transaction fee will be attached to your transfer - or 25 CoinJar Points if you prefer. This additional fee will be taken from the same account you’re sending funds from, and will be included in your quote as you make that payment.

Behind the scenes, CoinJar will then automatically attach an appropriate transaction fee depending on the amount you’re sending and the current blockchain congestion level. This transaction fee will be calculated dynamically to ensure your bitcoin transfer receives confirmations on the blockchain as promptly as possible.



Using CoinJar Points to cover transaction fees

When making a new outgoing bitcoin transfer, you can use 25 CoinJar Points to cover the cost of the transaction fees. For reference, buying or selling 1 bitcoin through CoinJar will earn 100 CoinJar Points - enough to cover 4 seperate outgoing bitcoin transfers. Similarly, using a CoinJar Swipe for 5 seperate purchases will earn 25 CoinJar Points - enough for one fee-free outgoing bitcoin transfer.
