I had made a tx with blockchain.info wallet and it don't confirm in 10 days (it is not double spend, paying 1 satoshi fee) and I can't use the coins now. What can I do?
blockchain.info will broadcast your transaction as long as it is not confirmed. if you want to change the fee the easiest way is to wait for about 48 hours till the funds are returned to your wallet, then before bc.i sends it again you can double spend it with fee.
