You should first find reliable source for your data. In a matter of 20 seconds there were around 80 sale orders executed from $600 to $608 for all prices, not just $600 and $608 like you posted. Totaly wrong. Why your stop loss was executed at $608 and not $602? There was large market order above your price and when it was finished and all other stop loss orders before you executed, it was your turn to eat the asks at $608.
Perhaps bitcoinwisdom isn't the most reliable ticker for accuracy of information. But my accusation stands. Bitfinex front run and commit insider trading. No doubt the process is much more convoluted and better concealed than my eyes can detect. After all, these guys have bots with access to all the key information on trader's intentions. But I know when I have been had. I knew it before but like a fool went back for more, albeit with just an experimental amount of BTC.
Look back at the whole debacle surrounding MtGox and how often Karpeles had apparently proven that all was well, that Gox was solvent, that the banks really had placed restrictions on Gox but all the money was there, etc.....nothing but bamboozlement. Bullshit baffling brains.
I find only you arguing about bfx scamming. On the other side many of users were talking about gox. Yes, there are bot manipulators on bfx orderbook, like there was also on other exchanges, but I haven't spoted any scamming. Use this kind of large orders to your advantage instead of being hurt by it.
