The very fact that lottery prize money is rolled over makes it more attractive. Because people like to have a chance to win $1,000,00 rather than to win $1,000. Every month as the pot becomes bigger and bigger, more people start joining in.
This is akin to small society lottery. Small is the USP. The odds of winning in small pool is higher. There are many people out there who are happy with small things. Small, affordable and transparent. [/b]
It will be like a marketplace. The Lottery creator will decide what will be ticket cost, Upper cap, Draw date etc. The platform will also put a limit on the higher cap. Based on the cap, the platform charges will differ. Say i want to create a lottery of 300eth, then the creator should shell out more platform charges, apart from giving 5% of the collection charges. If it is less than 100eth he should be able to do it for cheap.
I doubt thats the case with lottery though. People who buy lottery, do so in hope of a major payout.
