I really lile loterry because that is one my favorite game in the gambling world. Im not win a huge amount in loterry but only the consolation prize but maybe bitd.do is my lucky to win huge amount in lottery.
About the referral I likee it becaude you offer a huge percentage and maybe that is nice move to get more players that can play to your site and you help them to earn money if they invite a player it is a win win situation.
we're planing to lunch the chat in a couple of days ,
hopefully it will attract player to stay for a longer period on every visit
Dont forget to monitor the chat once it is ready. At least you need a chat moderator who can monitor the chat to avoid spammers especially spamming for referral links of other sites. Some useful feature such us tip, pm, or rain would make the chat more attractive and it may make people stay longer on your site.
