How about activity token project? if you can't mine the coins you have mentioned, you might as well buy my activity token, every time I put some sell orders on Waves decentralized exchange, my orders would get canceled the next time I'd login to my Waves wallet.
I don't have any whitepaper for my token, because people already know everything there is to it, Bitcoin killer, much better and faster and cheaper, it will change the(my) world.
You just buy them, I will do the rest and would tell you that my tokens are fee-less. on paper, they all are really something, you have to invest on every token, coin. there is no useless coin in crypto, they are just selling you the future of crypto currencies cheap, nobody would ask them, why are you selling them? why don't you keep them for yourself?
I'm keeping my tokens for myself, they are the future right? a man has got to eat right?
Why would you sell 100 Million coins for $0.01 each and then *deving them into something worth $1 to make others rich? you could *dev them and then sell them for $1.
