Just keep in mind that the major bitcoin exchanges act as tumblers, and SR acts as its own internal tumbler several times over, so it would already be almost impossible to trace-to-origin all of the bitcoins you bring on here (or even a small percentage of them). The amount of resources it would take to track down even 10btc would have to be pretty staggering, and then you need timestamps and such to verify everything.Basically, someone could see that bitcoins made it to SR, but not what they were used for. Or that they were leaving SR, but not what they were used for.If you have your Bitcoin client set up to run over Tor, that is usually enough. I do not recommend sending your coins straight from exchanger to SR, though - routing through one or two different addresses is always a good idea. Same goes for outgoing withdrawals of BTC.You aren't fucked for several reasons. one being that you can trace the payment path/block chain on bitcoins, but every paper I have read just gets you an address in the end, a point of origin. They still can't crack the encryption to actually identify someone on the other side, only acknowledge that "the entity with this address did sent these coins here". Your purchase on SR itself would be virtually impossible to trace, and I would think that LE is spending way more time tracking outgoing BTC from SR to nab sellers than incoming for small time buyers (maybe if they saw a few grand coming in they would look twice on the assumption it's a bulk buy for a f2f seller).I recommend setting up another mtgox account often, just use a throwaway email address and use it for a week or 3, then open a new one. Or with any other exchanger. No matter what your Dwolla is going to have your real personal information becuase it is linked to your bank account, but that's fine. They are doing $1million + a day in volume right now, and a lot of that is small-time amounts right in your general region, so it's pretty easy to get lost in the fray. Especially since they are growing pretty fast and have some big shit planned for the next couple of months (I wish I could invest in their company because they have some solid ideas and are basically creating a secondary payment network that completely circumvents the existing one. It's pretty revolutionary).You have to worry a lot more about buying from good sellers, because I'm sure there are more than a couple LE's accumulating buyer addresses on here (if you lurk the forums you will see some funny things have happened over the past few months), and of course using PGP for sensitive information. If you take just those steps, it would be impossible to prove that you intentionally attempted to receive drugs in the event of LE bringing the state's violent hammer down. The rest is just circumstantial evidence, and for all anyone knows you decided now would be a great time to invest in this new phenomenon called bitcoins and threw them into a secure wallet so they can go up in value.....
