Even if the ticket cost is 0.15 cents if you compile all the bettors money plus additional users who buy many ticket still its a huge amount came from all the bettors. But since this is new posted here I can't blame the user above post some malicious statement regarding on them since they don't have reputation yet so maybe its good to see them how they roll first before we participate on them.
Yes, you are right, participation in any lottery is a risk and a matter for those who participate in it, but also the responsibility of those who organize it. In the case of Long, it is suggested to simply download their wallet and send their address with a personal message on Twitter and get free coins to participate, and here it is rather just marketing to attract new users, nothing more. The coin is traded more or less actively on only one exchange, there is talk of listing on the coinsbit exchange in mid January, so the campaign has the status of a promotion, but this is my opinion.
What is your main motivation why you are supporting this lottery platform? Are you by any chance getting something out of this? Sorry for being straightforward. But you will not waste your time here if you are just doing this totally for free to support this project.
