you can add that the audience in this market is also extensive: according to the same statistics, in the USA more than 60% of the population has played in the lottery since the age of 18. Just imagine: the Americans spend $ 50 billion annually on buying lottery tickets. At the same time, the business model of this area does not go on the Internet: this is the very traditional model where all funds go to the organizers. I would be glad if that changed.
this, I think, is the merit of the blockchain. It opens up new opportunities for the development of such projects. In addition, a nice addition is that NeoGame works under the Ethereum blockchain, where all funds are distributed without a trace according to the intended and available algorithm, which is specified in the smart contract.
