If you were going to mine to launder money, wouldn't you have to launder the money to buy the mining hardware?
Craziest reason to mine ever. Also, lacks understanding of IRS.
No, because there's no link between the mining hardware and the coins mined. A new coin is a new coin. There's no trace of who mined it.
However.
If you're mining on a
pool the pool could keep a record of your IP and associate your address with the IP you were using to mine from. You could use TOR, but isn't it likely that most of the TOR exit nodes are run by the NSA anyway?
The only way to get totally untraceable coins is to solo mine, which is pretty risky.
But then you don't have laundered money, you have "clean coins" but you still don't have an explanation for where it came for, which I believe is the main point of money laundering. You want a valid, legal source for that money, I don't see how mining does this, it certainly makes it less traceable though.
Since when is mining not a "valid, legal source"?
Actually - I was only thinking about someone who wanted to
buy illegal stuff. So, if you want to buy something off silkroad, or donate to wikileaks and don't want any way for the coins to be traced back to you.
However, you got coins buy selling something illegal, and don't want to see those coins used to find out who you are (by loading them into MtGox, for example) then you could buy a miner and then use the miner to generate clean coins.
I hadn't thought about that "use case" until just now.
And yeah, it's true you wouldn't have an explanation for how you were able to afford the miner, And if the government was investigating you they could go to the mining company and ask for the TXID used to purchase the miner and start tracing back the transactions and IPs involved.
However, it would make things much more difficult to trace overall. You could mine on address A, transfer a little bit to address B and then spend that. No one would know that address A belonged to you - they would only know that A sent btc to you. They wouldn't know why.
But, let's imagine you're a government Agent. You think bitcoin user X has a bank deposit that you think is suspicious. Think about all the steps you have to go through to track the person down.
1) Look at the bank transactions and see it was from an exchange
2) Go to the exchange and see what address the coins came from
3) Look up the address and see where the coins came from, see the address you mine from.
4) Supena the mining pool for the IP address used to mine. Okay, what if your mining over a VPN or tor? Lets say you do all the work to track down the originating IP address (Maybe the NSA stores a record of all consumer IP traffic in their yottabyte data center. You look up the time stamps and see if bitcoin user X was online at the time, and sending traffic 'consistent' with bitcoin mining. You can really only do this because you're looking at a specific person)
5) Okay step 5 you see what IP address was doing the mining based on guessing from tor "timing".
6) you get the physical address where the mining took place from
7) If the machines are still there, you can find out what company sent them.
8] Do the machines even have serial numbers? Avalons don't, as far as I know. maybe some of it does.
9) Okay, so you take the serial number and you find out who the company sold it too - oops someone totally different since you bought this machine online
10) Okay so you track down the person who sold the machine to user X and get the TX id used to buy the miner from them. If they even kept records.
Aaaaaaaanyway, you see how much work this is and why the government wouldn't bother except in extreme cases. It wouldn't be perfectly anonymous... but whatever.
