Are there any miners in NYC that would be interested in taking cash for BTC on a semi-routine basis? I am looking to use BTC as a regular mode of cash transfer for business, but would like to see if there are BTC suppliers aside from the exchanges that could help facilitate regular purchase of BTC.

If you are interested, please send a PM. Would be looking to purchase ~$2,500 worth of Bitcoin every 1 or 2 weeks, and willing to pay a premium equal to MtGox/TradeHill/etc rates.

Just as a friendly heads-up: remember to meet in a public place (at least the for the first trade), and make sure sure you wait for at least one confirmation to eliminate the risk of the person pulling a Finney Attack on you.

What's a Finney Attack? Sounds nasty - does it involve a knife?   Grin

Basically, the person generates a block in which they move all the bitcoins from address A to address B, but they don't broadcast it to the network. Instead, they make the transaction with you, where they send you the bitcoins for the trade, also from address A.
As soon as you accept the 0-confirmation transaction, they broadcast the block, and that transaction takes precedence because yours wasn't included.

This has only gotten worse lately, as the attacker can purchase a ton of hashing power temporarily for that one block using a service such as GPUMAX.

Long story short: don't accept 0-confirmation transactions. Ever.
