Have you ever wondered what happens if your Bitcoin transaction is not confirmed? The size of the mempool is constantly growing in the course of the Bitcoin halving. As a result, some transactions are delayed up to several weeks while waiting for confirmation.

The Bitcoin Halving on May 12 this year has caused quite a stir in the Bitcoin mining operation. Due to the lower block subsidy, the operation of mining rigs is now only worthwhile for miners who can obtain electricity at extremely favorable conditions. The hash rate in the network has decreased by 21% since the halving. However, anyone who has sent BTCs in the last few days will have noticed that transaction fees have soared.

In the current 313th Difficulty epoch, the miners are even already 32 blocks or 23% behind schedule. As a result, many transactions remain in the mempool for days, because the miners cannot keep up with their efforts to integrate them into blocks. In order to get the transactions confirmed more quickly, you have to dig deep into your pocket. So if you have sent BTC with too low fees in the last few days, you cannot expect anything good. Until the mempool is completely dismantled, it will probably take at least until the next Difficulty Epoch. In other words: Some UTXOs could remain unconfirmed for up to two weeks. But if you are in a hurry, you can pay Miner directly to include the UTXO in the next block.
