So I have an unconfirmed transaction since almost a week now. The transaction ID is fd82fb9711afc48623fa13fa3963121f88160afe56fc968feaf02e5f73e7b764
This is due to the fact that exchange cex.io to save money bunch a huge number of requests in a single transaction which effectively brought down the satoshi/byte.
Today when I searched for the transaction in a few blockchain sites it says transaction Not found. Sites like blockchain.info show the transaction but multiple sites like live.blockcypher.com, blockchair.com, blockexplorer.com etc all show transaction missing.
What does this mean? Is it that my transaction will be dropped finally? I prefer it being dropped as this will never get confirmed. What is the sure way of checking if a transaction is dropped?
