Trying out Bitcoin for the first time and I've ran into a problem with unconfirmed transactions. I decided to do a "test run" and send $10 worth from blockchain to bitpay wallet. The bitpay wallet shows the amount being received, but continues to say the transaction is unconfirmed. It has been three days and now when I try to view the transaction on blockchain, I receive an error message saying the transaction cannot be found. Is this just due to the large amount of unconfirmed transactions and the small amount of bitcoin I am receiving or is the transaction gone and I lost the amount? Any help is greatly appreciated!
