btc-arbs: I've been using it, and promoting it. The opportunity for arbitrage is real, the numbers and deltas are factual. I'm keeping a blog update at
http://notnull.org/bitcoin-arbitrage-news/bitcoin-arbitrage-updates/ and in the event I get screwed, which would really only be if they steal and bail, I will certainly be posting. But there is little reason too, there is far more upside to stick around and continue the arbitrage strategy, the difference between the markets is significant, and consistent.
The idea of an annual return, assuming 2% every single day, is huge, but it won't be 2% every day. Yesterday it was 2.28% and a couple days prior it was .4%. If someone was to compound the balance by 2% every day, for a year, consistently, the return is enormous, alarmingly huge. I get it, but the difference of the price of the commodity between the exchanges they use is clear and consistent, why not operate legit when the chance to make a clear daily return is right there? They would only need to make 1 or 2 trades a day, sounds like a chill methodology. It's 1.4% this second just looking at it.
IMHO: It's just logical math, if it's a scam then the joke's on me, but I sense the trolls are just jealous and so jaded now after Gox that any investment with any promise is too scary to consider objectively.
Let the flames begin.....it's not that it is too good to be true, it is just plausible and seemingly good to go!
