I understand paying low fees will result unconfirmed TX but my case is different.

Bitcoin Core wallet shows tx, shows the fee I'm paying, but I cant track it on blockchain, it only shows up on Blockcypher without a fee and and very low confidence.

Transaction total size: 6977 bytes
Output index: 0

I used the CUSTOM Transaction fee section in transfers page. did not put the minimum.
My calculation should be fine I believe, 0.0049BTC fee should be 497,000 satoshi so divided by 6977 bytes gives 71 satoshi per byte . Please let me know if I am doing something wrong here.

It has been a day with no tracking nor confirmations.

Should I cancel the transaction ? ( abandon transaction is grayed out ) . I backed up my wallet before doing the transaction . Using Bitcoin Core version v0.15.0.1 (64-bit) on windows 7.

Not sure it is a wallet problem or if I did something wrong. Wallet show 0 BTC now , so can I just cancel this without losing the btc.

Thanks Alot for help .
And sorry if it a duplicate post, I couldn't find one similar.

Hi, I had no drive space on my computer because of sync so I copied the Bitcoin folder from appdata to another drive. I finished the resync successfully .
Problem is I had 0.98 bitcoins now showing 0.51 in my wallet.

any ideas appreciated

Thanks Alot
