You should include higher fees if you wish to have your transaction processed quickly. A miner will do everything in their power to complete your transaction as soon as possible. However, if processing time is not an issue for you, you should not include higher fees. In the course of performing a bitcoin transaction, a crypto user includes a transaction fee to be paid to crypto miners in exchange for their labor in verifying and adding bitcoin transactions to the blockchain.
As a reward for their work, miners receive a block reward and transaction fees. Miners add transactions that have higher fees to the blockchain first since each blog has a limited amount of space. Unprofessed transactions are placed in a pool called the Bitcoin mempool. If users are in a rush, they might choose to pay higher than those who are not in a rush so that their transaction does not end up in the Bitcoin mempool.
Unconfirmed transactions or long wait times indicate that your transaction has not yet been processed. You may have not included a higher fee in your proposal or the network may be congested. It is also important to ensure the address you provided is valid and accurate. Depending on your address, the Bitcoin network will either reject or confirm your transaction. If a transaction is rejected, the funds will be returned to the originating address within one to seven days.
You will not lose the money if you include fewer or no fees at all, send bitcoin to an invalid address, or for any other valid reason your unverified transaction is rejected. Funds, however, cannot be refunded when bitcoin is sent to the wrong, but valid, address. It is preferred to store your Bitcoins in the secure Bitcoin wallet.
