Recently a man was deceived by someone who had change the electrum source code on an old version of it. He lost 1400BTC(!)
I had made a similar question in the past, but the answer didn't satisfy me. Why should that hacker use a mixer? If he try to sell the bitcoins from his main address (the one with the 1400BTC) he will get caught, because he will prove that he is the hacker.
If he send 1BTC to 1400 owned addresses, though, no one can prove that the person that owns those 1400 addresses is the hacker, right? They can only ask them where did you get that one bitcoin.
I laughed at 'creating 1400 addresses'. I dont think anyone, whether your a hacker or not, would have that kind of time to sit down and create up to 1400 cryptocurrency addresses and then start moving one Bitcoin to each of them, like youre going to do that up to 1400 times, lol like who will have that kind of time?
By the way, I think if youre creating addresses on the same computer you can still be traced not hundred per cent sure about this though, just saying; but if those addresses are running on the same comp, you will caught. But no one has that time, so they will make use of mixers to escape.
