3rd and last I know how to create tx and relax for sure where coin will move to my assign address
THB this sound like a bait and bullshit, unless you are a miner or have some accesses to miner resources in somehow.
Besides that there is not an other method to do that.
I been collecting some dust inputs from leaked private keys and that's actually very difficult to do because other are doing exactly the same with those address... so there is no safe way to move an address with leaked private key with 100% of certainty to win that transaction.
