Re: Bitcoin arbitrage, quite profitable BTC investment, make 1-3% ROI per day

But as anyone here I don't know what they're really doing,

If you dont know exactly what they are really doing, and they are promising/paying unreal profits, constantly trying to attract more and more funds with referral programs etc, it should be glaringly obvious what it is they are doing.

I cant believe someone who's been around since 2011 still falls for this. Tell me, how many other ponzi's did you get suckered in?

at this right moment -like ever- the delta between bitfinex and btc-e is 5$ = almost 1%. Can you believe it?

1% price difference. Subtract trade fees. Then divide by 2 (because you need BTC on the high-price exchange and the same value in USD on the other). That's the theoretical profit if you can utilize all your funds. In reality, you'll have most of your fiat stuck moving through the slow international banking system from one exchange via your bank account to the other exchange.

If you can translate a consistent 1% price difference between exchanges into a daily 0.2% profit then you're doing an amazing job.
