A fellow BitcoinTalk member - RyninDaClem - has created a free paper trading game for the Bitcoin market:
It's a nice way to put your trading ideas to the test without needing to use real money.
You sign up and receive $100 in play money. You are always either all-in, or all-out. Trades cost 0.2% commission, limit orders cost 0.15% commission (of your fake money).
There is a leaderboard...whose rankings have been changing quite rapidly amidst all this volatility!
Here's the link:

Again, the game uses play money, and there is no cost to sign up. Hope to see you all there - not too shockingly, I'm Chainsaw ;-)
Comment below to let me know what your handle is, and what you think the market will be doing in the next few days.
And be sure to follow me if you enjoy staying plugged into the Bitcoin market's behavior. As volatility heats up, I'll be providing more daily analysis and updates.
