If i have bitcoins only from mining and if i'm making transactions with only a friend, so only he knows who am i, police and other institutions, cant get my ip adress.
If you're just mining and trading with a friend, police and other institutions have little reason to get your ip adress
they may have, if i trading with him marijuana, amphetamine and other drugs + TOR, there are some ways to make anonymity
I know dumb people can't make it anonimity, but if you think a little , make some tricks, you will be anonymous, and be able to selling drugs, laundering money, avoid debts, who cares haha, there are two sides to every story, fuck government!
just laughs, peace people!
