so the dusk tokens will be released initially on the market as erc20 and only after about six months there will be a possible swap, i hope the team make agreements with bitfinex so that the swap can be done directly on the exchange, i think a regulating of sto on a blockchain decentralized is quite difficult...
Kucoin supporting security tokens? This is a good exchange for swap (as I know they swapped a lot of coins after mainnet already). So hope DUCK will be listed to Kucoin as well

I don't know if Kucoin supports security token (but I don't think so), but I can tell that DUSK token is an utility token (as far as the community manager told)
