The 10 Users Each Send Me The Organiser 0.01 ETH
Yeah,right.
I have nothing against the raffle/lottery business model,but there's no way your idea is going to work.
I have some suggestions:
1.Use smart contracts and a legit way of randomized winner picking(that can be verified)."Send me your ETH,because I'm the organizer" doesn't work.People aren't dumb.
2.I bigger portion of the "ticket pool" must be used for advertising or maybe there should be a way to incentivize players to share your raffle on social media and drive free referral traffic to your raffle.
3.You have to be as legit and trustworthy as possible.There must be no doubt about your legitimacy.
The raffle winners must provide good reviews about your raffle.
