The number of transactions in Bitcoin blockchain is increasing day by day. Too many transactions can not be put in one block and therefore sometimes transactions get stuck. This means that it is stuck in transaction line and is forced to wait for the overloaded operator to verify this transaction. Of course, after some time the transaction will enter into the block, but it may take too long.
In general, the miners primarily carry out the transactions that have the highest pay commission. The rest of the transactions, which are smaller than others, will not be verified until the commissions are listed on the so-called market / auction. Fortunately, there are means to which your bitcoin transaction does not have to be in queue for days or even at all.
Before transaction:
If you want your transaction to be confirmed soon, the first thing you should do is to indicate your transaction to a higher commission than it is in the market. A lot of wallets already have a function which offer you a commission fee recommended to avoid your transaction getting stuck. If you want your transaction to be faster, indicate a high commission. If transactions from your wallet get frequently stuck, try to update the wallet or change it altogether.
Web sites such as 21.co are monitoring the network, and also recommend the amount of bills you have to pay on the bitcoins and will also count on the expected time to complete the transaction.
After transaction:
If you have already sent the transaction and it got stuck in the network, you can skip the queue. This feature is called "Opt-in Replace-by-fee". This feature will allow you resend the same transaction, but with a higher commission fee. It should also be taken into account that this transaction depends on which miner will gain the following block because all miners do not operate with this function. Not all wallets have The 'Opt-In RBF' feature, it is only used by two: ELECTRUM and GreenAdress.
If you do not have the above function, then the speeding operation will be a bit complicated. When sending bitcoin, you not only send it to the recipient, but also send the change back to you. You can even spend it. Some wallets give you the right to spend the change even before it is confirmed. At this time you send this threshold and indicate a relatively high commission. If both transaction fees are high enough, the latter will confirm both transactions in the following block. If your wallet does not give you the chance to spend your change, you can send your balance back to your address as well with a higher commission fee. This transaction has already been tricky and will soon be confirmed.
There is another way that VIABTC offers to customers. Go to their website and go to the 'TRANSACTION ACCELERATOR' section. Write your transaction identification number in the specified field and they will prioritize your transaction. Note that the volume of transactions must be at least 0.1 Mbtc/kilobite. Since the VIABTC tank makes up 7% of the entire network, you have a good chance that the transaction will be accelerated. This service is limited to 100 transactions per hour. The service also works for the transaction recipient.
