Wait - so you're selling 0.1 BTC for only 0.99 euro? IMO the auction won't go anywhere near the current price of bitcoin, so you're basically just making a loss... or are you planning to run away with 1 dollar?
0.99 euro is the starting price and should no additional bidder show up then yes, 100mBTC will go for that price. No catch nor scam.
I do expect some more bidding but if that doesn't happen I will certainly not run away with my fortune of 0.99 Euros!
This is a legit experiment in applied crypto finance so feel free to bid.
