if i sent btc from market to electrum on tails, to exchange site (ie coinbase) and then sold that for cash in my bank, can that be traced to my identity? it seems it depends on the coinbase address being tied to my name but i dont know how someone could know that unless they already know who i am. or theyre the cops and request the info.
You at least need to send them through one tumbeling service. That will break any link of those coins coming from a market. Market > Tumbler> Electrum or whatever> Coinbase. Always remeber how much is your freedom worth??
