In the “View” screen, you can see various information besides transaction ID:

  1. Status: Unconfirmed, means not included into any block.
  2. Position in mempool: 5.85 MB. Basically, how far your transaction is in line. 1 block = 1Mb. Every 10 minutes, one block is confirmed. So here we can see that our transaction can be expected to confirm within an hour or so.
  3. Amount received: 0.00025411 BTC or transaction amount.
  4. Fee. How much sender paid to send this transaction.
  5. Size. How much of block space this transaction occupies.
  6. Replace by fee: True. Means that sender can increase fee to either speedup the transaction or double spend it. So, until the transaction is Confirmed, it is not safe to ship any products/services.
  7. Locktime. Is the block height or basically the block number to which this transaction is included.
