Amazing do they have a limit on how many coins/tokens there could be listed at the moment? i am pretty sure a lot of tokens would love to get listed on ONAM's exchange.
I dont think they have a hard limit when I talked to them on telegram they were taking suggestions and are working for more coins but want to maintain regulatory compliance so have to work around that I think with coin platforms
Even though it's take few clicks to list at Onam exchange, but I am sure Onam will be doing lot of screening in background before approving any tokens listing.
