Actually，you donot know what i said. you only recieve nuds for miner,and never send nuds to another people,is it right?? every time you send ,you will get one or more strange new address,i sent 10 nuds to dev,the blockchain appear i sent 100 nuds,90 to an strange new address,10 nuds to dev.i sent 50 to dev at the second time,this new strange help me send 50 to dev,and 40 to a new new address...all this two new strange address is not listed on my wallet recieved book!!!
For what i understand these are your change addresses (used by coin control). When the block explorer recognizes RTR0 on a proper way these addresses can be linked to your main address (if i understand correctly). Maybe te DEV can tell us more?
