Let me just say, the main reason for the establishment of airswap is because of security purpose. This exchange is a decentralized exchange which the need of registration is not required. During the time I used the exchange it only needed me to just provide my Walker connected to the exchange . The exchange has done a very nice job on the amount of fee it charges, the withdrawal fee seems very low and cheap unlike many other exchanges. I was always happy that my funds can't be hacked. I will advice other people to use the exchange if in need of their services. The exchange really cost me low. Thanks for reading
