I withdrew my money from my Mt.Gox account using SEPA bank transfer last Thursday but I haven't received them yet. Does it usually take over 5 working days for SEPA payments to go through?

Currently there's no real economy built around Bitcoin. Bitcoin value is purely based on speculation and it has become a ponzi scheme. New investors pay the profits of miners and early adopters. If new investors stopped investing in Bitcoin the price in $ would drop like a stone. "Worth" of all existing Bitcoins got up to $200M before this price drop occured.

Now ask yourself how can Bitcoins be worth $200M when there's maybe couple a million $ worth of stuff that you can actually buy using Bitcoin? Why do people invest in Bitcoin? To actually use them or to get rich quick?

$10 Bitcoin is still a massive bubble, it should crash to around $1 or less to be on solid ground. This would drive most of the speculators out and stabilize the currency a bit.

Maybe Phoenix would rise from the ashes.

So I'm new to BitCoin and I though about contributing something to the BitCoin economy. I'm trying to sell something and then buy something to see if BitCoin actually works for these kind of transactions and if the economy has any potential.

The game is indie western multiplayer shooter and I have 2 extra copies of it from 4-pack:

The standard price of the game is 8.99€ in EU and $9.99 in US so I think asking 10 BTC for each copy isn't too much.

If you feel the price is too high offer something less and I'll consider it!
