So far not good with my experience with arbitragecoins.com.  I have requested a withdrawal of 2 LTC but its been two days and no one bothered to reply on the online chat.  Before that, I was chatting with a Mark.  I was gonna actually use my LTC withdrawal to buy BTC and deposit with them again but this is scary that they, so far, hasn't replied me though I can see that their chat is online.  They should handle withdrawal requests first as this is the main thing with these kind of service.  It shows the lack integrity of www.arbitragecoins.com when they don't reply to you after you make a withdrawal request.  PM me you don't believe me and I will email you proof.  So far, www.arbitragecoins.com feels like a scam.  If they return my LTC coins, I will retract my comments here immediately.
