Acquiring bitcoins is not difficult. Using them anonymously is moderately difficult though, at least at first. See the thread in my sig on Bitcoin and anonymity.- You ideally want 2 Factor B$ Anonymity.1. Your entry into the Bitcoin network i.e. your purchase of bitcoin, is not linkable to you.2. Your traversal across the network e.g. to SR, is not linkable to you if you screw up part 1 or decide it's too difficult.You achieve No.1 by the way in which you acquire bitcoin.You achieve No.2 by laundering your bitcoins.In RL, drug dealers launder the proceeds of crime after the transaction has taken place.On SR, it is done before and after! LOL!Using both factors together, it is impossible to connect the financial transaction of obtaining illegal drugs with bitcoin to your person. Again, I recommend you read my thread in the signature.Also, look into bitcoin-otc and local bitcoin.
