I see, that I can send btc to my own adress in the same wallet, but it still asks about higher fee, how large amount I must send to consolidate things?
It will always ask about the high fee until you send. In order to consolidate, you must send, and thus you must pay the fee.Thanks for a fast reply
And that means when I send from my wallet to my wallet some amount it will consolidate unspent outputs? It will fix everything, or I am missunderstanding it?
Yeah, when you send from your wallet to the same wallet, it will consolidate the small inputs but you will have to of course pay a higher fee due to a lot of inputs. You may need to do this in several rounds depending on how many inputs your wallet has in total to avoid hitting the limit.
