What to Do if Your Bitcoin Transaction Gets "Stuck"
The number of transactions on the Bitcoin network has steadily increased over the years. This means more blocks are filling up. And as not all transactions can be included in the blockchain straight away, backlogs form in miners’ “mempools” (a sort of “transaction queue.”)
Miners typically pick the transactions that pay the most fees and include these in their blocks first. Transactions that include lower fees are “outbid” on the so called “fee market,” and remain in miners’ mempools until a new block is found. If the transaction is outbid again, it has to wait until the next block.
This can lead to a suboptimal user experience. Transactions with too low a fee can take hours or even days to confirm, and sometimes never confirm at all.
But there are PAID and Free bitcoin transaction acceleration services available now which you can use to keep your own transaction from getting stuck.
Bitcoin transaction accelerators
- https://ViaBTC.com : ViaBTC pioneered this service as a protest against the current limitations on the Bitcoin network. The service gives priority to the user-submitted transactions into the next mined blocks by the ViaBTC pool. The only requirement is that your transaction include a minimum fee of 0.0001BTC/KB.The free-to-use nature of the service has made it widely popular as every hour, the number of transaction requested reaches its limit and it is common be presented with the message “Submissions are beyond limit. Please try later.” on the top middle of the page, this means you will have to wait for the next hour for a new submission.
After submitting the transaction, you have to wait for the next block to be mined by ViaBTC Pool.
- https://confirmtx.com: Offering a similar service to the one provided by ViaBTC, confirmtx charges a fixed fee of only $4 for transactions larger than 500kb, all smaller size transactions are accelerated for free.
