Since you are testing the BETA version and very new to the market, my suggestion is to giveaway registration bonus (without any need of depositing, may be to some number of users only. Say first 500 as example) with some very hard goal to achieve like 30x play through of the initial bonus for minimum odd of 1.8 or 1.9.
This way new users will be attracted to have the free bonus.
You ruined everything by saying "with some very hard goal to achieve" lol
OP I like some functions you offer but to be fair website looks very poor, better to get some good template, look your opponents, their website looks very attractive. Also when it says: 17 Available Matches, does this means we are limited in offered games? Because can't find more than one page too. It will be good for your business to make filter for games, for example make one block for La Leagua, another one for Serie A, Champions League and etc. This is really must to have even for beta project. Also include some details on betting, for example number of corners and others which top casinos offer.
