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?
1 satoshi fee?
As far as I know, the mini fee is 1000 satoshi.
1 satoshi fee?=no fee at current.
There isn't actually a thing called "minimum fee" but there are "recommended fee". The least amount you could ever use is 0
BTC. FYI: 546 satoshis is dust limit and a transaction shouldn't include less that that and using a fee less than 546 satoshi isn't a good idea than using 0 satoshis. I maybe wrong though.
