Iam trying to decipher what they stand to gain by accepting your shitcoins that have no value. One thing I am sure of is that, there is a way they benefit, which is far more than accepting your shitcoins, but you should also check and be careful, so that you are not negatively affected.
I think they have no plans to do anything with the tokens actually....just want you as a player on their platform......look at the tokens they ask for this week, some of them with 0 daily volume....
