Such listing can be considered unofficial since the Lattice team already cut ties with the hoo exchange I think it will be better people are aware of that and trade on their own risk, this exchange was not transparent is the reason why the Lattice team severe ties with them but they still list it anyways, to me bithumb will be a better option, kyc not needed to withdraw small amount.
For me, if the team say so, I think I have no choice to obey it for safety. I did not want to trade with a trouble that waiting for me, just like that. and yes, Bithumb was the best so far to trade LTX, so friendly to do wd off small amount. but afaik, KYC is needed to making withdraw of bigger amount.
