"You have to own 50m NoOne tokens to participate"
RED FLAG. I have taken a look at NoOne and it seems like it is not a serious project, has absolutely almost no community and is demanding people to buy their tokens to participate in some BS riddle competition. I cannot find any info on the team or even a whitepaper of any kind. If I had to guess I would say this looks like a scam that will run away with the money they got from duping contest participants into buying and holding their coin.
I WOULD RECOMMEND EVERYONE TO STAY AWAY until there is more info that proves the legitimacy of the team, the project or at least a verified escrow service/person who holds the winnings until there is a winner.
DO NOT CONNECT YOUR WALLET ON THIS SITE OR GIVE AWAY YOUR SEED PHRASE
You obviously didnt look hard enough and can calm down with your red flags... The community is small because its a new project but there are over 700 holders and growing.
The project is SAFU:
Furthermore, there's a Play2Earn game launching that will bring a teamed aspect to the riddles, where prizes are distributed automatically to the winning teams.
As for winnings, the prize wallets are all linked on the riddle website. When you enter the correct answer to the riddle you're given the seed phrase to the wallet.
