Recently I had a quite scary experience with bitcoin transaction. On Tuesday morning, I sent 0.016 btc with preset default Electrum fee (it was 50 satoshi/byte at the moment). Then after 48 hours of waiting and tracking my transaction on blockchain.info, it suddenly dissapeared and I got a message
"Transaction rejected by our node. Reason: Transaction was previously accepted but has been pruned from our database.". I thought the funds should come back to my wallet, but after 72 hours, nothing has changed. I needed to send that amount, so I decided to send it again in another transaction with much higher fee (140sat/byte). After I sent the second transaction, the first one suddenly changed and it showed I have 1 confirmation. I went to check it to blockchain.info and my first transaction was there again, despite the fact they wrote it was removed from their database. Then, after 10mins, both of the transactions were confirmed..

Oh bitcoin, you make my hair go grey.
