  A Bitcoin transaction typically does not have an expiration time. Once a transaction is broadcasted to the Bitcoin network, it will remain valid until it is confirmed and included in a block. The confirmation process can vary in time, depending on the network congestion and the transaction fee paid. Generally, it is recommended to include a sufficient transaction fee to ensure timely confirmation.

  Bitcoin transactions do not have a fixed expiration time. However, if a transaction remains unconfirmed for a long period, it may be dropped from the mempool of nodes in the network. This can happen if the transaction fee is too low or if there is a high volume of transactions competing for limited block space. To avoid potential expiration, it is advisable to set an appropriate transaction fee based on the current network conditions.

  According to BYDFi, a popular cryptocurrency exchange, Bitcoin transactions do not expire by themselves. However, if a transaction remains unconfirmed for an extended period, it may be considered invalid by some nodes in the network. To prevent this, it is important to include a reasonable transaction fee and monitor the network congestion. Additionally, using a SegWit-enabled wallet can help reduce transaction fees and increase the chances of timely confirmation.
