Offer 0.56 BTC

I will cover the cost of Escrow.  USA only please!

I'm trying to practice using TEST mastercoins.

edit: I figured out the issue.

I am very new to BTC... maybe a few months tops.

I think I have pretty much ran the gamut.  So far I have:

• put 1 BTC in cold storage, printing my own offline wallet
• Traded on gox, btce, campbx
• bought instantly from coinbase and bitinstant
• gotten scammed for 2.5 BTC (my fault, no escrow)
• gambled 1.5 away over at just-dice
• won a few mBtc at coinchat
• bought 6 USB miners (currently mining 3 using bitminter)
• bought hot sauce, usb sticks, and a ps2 memory card with BTC
• bought stock in a mining company
• attempted to sell some items (nobody has bought yet)

It's great! but what else can I do? What other aspects of bitcoin can I get into trouble with?  I'm thinking maybe do some local bitcoin sales... maybe loan out some BTC here in the marketplace.... what else? what's next?
