If my calculations are right I would break even when bitcoin goes down to 89$?
I prefer to sell the 100BTC now, and buy myself 146 if it really goes down that far...
... and sorry for spamming the thread - my initial observation:
What does the comparatively low difference between MtGox and BTC-E tell us?
Also it has been a loooong time since bitcoin.de and btcchina.com are dealing higher than MtGox.
