I noticed Aventus (AVT) while on the Airswap site, but when I tried buying there were no sellers around so I had to go to Mercatox instead. Also, I see where Paxos (and formerly itBit) has said they'd bring on gold and silver tokens in 2019; that will be of interest to me. I agree the MakerDOA (DAI) could be very big, but how does AST make profits on these popular tokens if from what I've read you don't charge a fee or am I mistaken? Anxiously awaiting new version upgrade this week or the beta test... not sure which it is.

EDIT1: In case you didn't get the upgrade link, here it is. https://instant.airswap.io/
Much better UI in my opinion, good job team Airswap!
