Anyone out there use this site for arbitrage? www.bestbitcoindealers.com, it seems like there are huge differences in price across exchanges. Nice that Exmo actually lets you cash out in Dollars as they always seem to have high prices 
EXMO is really pay high that one can take arbitrage opportunity but my fear is how legit the EXMO is as i am coming across it for the first time. arbitrage opportunities actually are mush available on must of the new exchanges but how trusted there sites is one of the thing we should look for as most exchanges platform or sites that has scam traders are those that offer wide range of differences in pricing of some major coins. I will like someone to Educate me more about this EXMO sites. thank
