...or the maker of a pipe bomb if they can't find the bomber (or even if they can, since there aren't a lot of legitimate uses for pipe bombs).
I can't really think of any use for for a cryptocurrency mixer than as part of a scheme for obscuring the true source of some funds.
I don't think it would make sense to go after individual miners for processing transaction initiated by a mixer, just like it wouldn't make sense to go after a bank for processing a legitimate-looking transaction that was part of some kind of fraud scheme that had no awareness of.
Money laundering (obfuscating the source of money) is actually a crime and for good reason. Obfuscating your internet history is not.
No, that is not the definition of money laundering. It does not broadly criminalize efforts to maintain financial privacy.
Money laundering means hiding the source of illegally obtained money.
That is NOT defined as money laundering. That is tax evasion.
I stand corrected.
This is probably the single most common use of VPN software.
I also sometimes use a VPN when an Internet hotspot seems shady, or provides a crappy connection in some way (spoofing DNS replies to insert advertising on NXDOMAIN, for example).
IIRC, Bitcoin doesn't make privacy the default. It's easy to trace transaction on its blockchain, hence the need for mixers if you want to obscure the origin of some cryptocurrency.
