If i counted right they have been given over 19 different currencies to give away in their games, to promote these coins. They have some other currencies, but over 19 of them they have been delisted just like that. And once a currency gets delisted, you have no other option than to swap them for their own PHT token.

Some currencies was there 6-8 months, others (most of them) only for 2 months. I wonder what the people of Stellar, Ripple, Doge, Holo, ETN etc think about that? They have given them bunch of tokens for promotion. Then they just disappear.

I wouldnt be so happy about that if i gave away crypto to some company with the promise of promotion...
