This bullshit. The topic and the question content is conflicting. When I saw the " biggest risk of p2p trading" as the caption of the topic I was thinking the op wants to tell us some of the tips of p2p I trading and unknown to me that he is even asking questions for us to tell him the risk of p2p we have experienced. Op you did try in this thread at all. Op then you have to changed the topic to suit the content.
Yes there is a very serious danger in p2p trading of Bitcoin and that is why everyone who is involve should be b careful because you don't know who is who behind the scene. Therefore you have to trade with caution.
