I sent 5 tx with mixin 0 and now, more that 1 day, this coins not on wallet balans but transations still unconfirmed, how i can cancel it or resent ? Thank you.
Wait 24 hours. Most nodes will then drop them.
Then you need to rescan your wallet to regain access to the coins and can make a new transaction. Instructions for that are upthread, or someone can repost.
This thread need Korean translation, I would add Japanese to this list, but there is still no dedicated section.
Looks like we do have some followers in Korea
