honestly speaking I don't. the only reason I buy tokens or coins is because of their future ROI. I buy them mostly at presale or immediately they get listed and wait patiently until I get the feeling the hype is over and trade them immediately to Bitcoin then forget them for good. moving to another wanna be bitcoin. so far I have made 3 digits in bitcoin from doing so and still holding. I don't care what the coin is use for, none of that is my business since I know they all will die someday and the only true cryptocurrency is Bitcoincash oops BITCOIN
