at first I was also confused, I once joined and got a tokpie token but from the news I heard it was very complicated to sell on their exchanges
and I haven't confirmed it myself, I asked a friend to help sell my tokens.
and also the difference in price with the cmc is quite different.
I had joined their bounty campaign recently , it's interesting because you can sell your stake and convert it with eth, If im not mistaking they had 14 bounty campaign since 2018 which 3 of them only failed.
I think what makes a lot of people do not use the bounty from tokpie well maybe they are holding a bounty campaign in a different place, not just in this forum, so that many people do not know that there is a very legit bounty campaign.
