Is it true that blockchain.info increased the miners fee? Or it's automatic because I have a transaction and I find it unusual.
The fee costed 0.0004 BTC
You can always set your own fee - if you don't feel like paying standard Blockchain's fee or don't need confirmation in the next block.
Standard and automated fee was incensed because users complained that their transactions are stuck ans'unconfirmed way to often.
This is not blockchain's fault that we are having 'war fee' right now and with new high bitcoin price fee rates seem awfully expensive.
