Xtheta exchange founded in singapore . Xtheta is an exchange which is aimed at trading spot,OTC and margin trading. If the exchange taxes such assets it means the exchange is advanced, hardly you see exchanges has this features. The trading interface of this exchange is responsive and easily used. The support teams are also very fast at replying messages. I am not too happy with the trading fee of this exchange, it charges both takers and makers 0.15%as of when I was still using the exchange. To me it seems high and also the withdrawal limit was still not satisfying and very high. I was a good tron trader in this exchange and I was able to withdraw 1550 trons due to it was too small.
