It's very simple, the value of this company is the jackpot. Once someone guesses 6 numbers correctly, the value of this company will instantly drop to nearly 0. If not, the tokens will slowly rise. Not my cup of tea to be honest, so i'm out.
The probability of this happening is on the other side extremely low, and it would rise only is so many other people would play that then the jackpot would also become much higher.
More people playing the lottery increases the odds of someone hitting the jackpot.
Also, they are misleading by saying you can win 70k ETH. They don't have that, they only have like 6k ETH. That's it. Plus, they only dole out 5% of ticket sales to the token holders, which is pretty low. And how to increase ticket sales? They are so many lotteries out there, people don't know about smartbillions. It takes a lot of marketing effort, and thus expenses, to raise awareness.
I just don't see the edge here.
