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?
If there is no confirmation FOR 10 DAYS they should've already cancelled it.. one with 0 trans feee, they cancelled the transsaction after 5 days
Its not possible to "cancel" a transaction. Bc.i could stop broadcasting it, but maybe the recipient has an interest in the transaction verifying. The recipient or anyone else could rebroadcast the transaction constantly in order to ensure that the network does not forget about it. This does not ensure that miners put it in a block to confirm it though.
