Hey I have seen your post history. If you are a Someone from the PCEX exchange team it's better you express the same before posting such advertising stuff. I am sure this isn't a genuine independent user review of the exchange. This isn't the correct section for such things. If you want to give some genuine advise to newbies it's better you don't advertise such things this would just end up getting you banned from the forum otherwise mention that you are from the team of this exchange.
