They are definitely scam ! They scamming other brokers to pay them money and promising them to put them on the top ranking !!!! If you see all tops are themself Chinese broker not well-known ! So many issues with them only paid to wiki to put them on the top ! Additional to that they post wrong info about other brokers in order to get the money from them and remove the wrong info !!! If clients who was victim of some broker report the fault to them they first ask broker whether they are ready to pay them to not post the information or not ! If broker pay them they never post bad review about that broker !!!! Clearly scam ! Open shop for their big pocket !
