Why Polonix when there are other trusted exchanges you can go for without having to fear for anything, if you at least go to the scam accusation board, am sure you would have encountered many threads that reports on this same exchange for one reason or the other, if you're seeing many only reviews talking bad about them, this shows also that there's high probability of them being involved in what others have been saying about them with their encounter i using it, i will advise you don't constitute the numbers of those complaining already about this same exchange, instead make wise decision and get a reputable one and if possible a decentralized exchange like bisq or hodl hodl.
