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.
AFAIK, a transaction must have all outputs above 5460 Satoshi to be considered as a non dust and have nodes relay it. If it's below that, nodes would simply not relay it. There are nodes which relays it but for nodes using Bitcoin Core, they don't. It is generally a bad idea to use 0 fees for anything below 0.1BTC since the priority would be so low that it would take a long time to confirm.
