That would explain why there seem to be so many bitcoinica buys and sells. I'm getting good at noticing and catching bitcoinica squeezes at the maximum possible spread.
I trade MtGox:
Buy and Sell the internet commodity known as Bitcoins!
Mt Gox charges a small fee (0.28 %) for each trade.
Your trading volume for the past 30 days is 51,616.02744263 BTC. If it reaches 100,000.00000000 BTC, your trading fee will be 0.27%.
Looks like I'm only about 2% of MtGox in the past month, having fallen a bit since things heated up 2 months ago.
Running out of reserves on bitcoinica can really fuck with someone's trading strategy. Do you provide any warning before cutting off traders?
