Some feature of your website are lacking.
How to know if there are other players online? through discord? Do you think that most gamblers would like to visit another website or channel just to know how many players are online? it should be visible to your website.
What if someone deposits and there's no one online? what happens to his deposit?
As earlier mentioned by other members above:
"You will be cashed out if you disconnect or close the page."which basically means that funds that had been sent out will automatically cash out or returned. I agree on the thing you had complaint that there should be at least some stat or counter
on how many players are online and how much NANO they have bet on. Lets say you had bet 0.1 NANO and other players do bet 0.001 NANO and others are in different too, which means
its really hard to have a matchmaking since amounts arent really the same so it would be better if does show amounts been put up by other player or else, this is just like
hide and seek thing where you do try to figure out others bet for you to match up.
