Is that how you'll advertise your casino? Are you really giving away bunch of money from your very start? TO ME, it sounds really too good to be true, I have some doubt about your honesty and fairness to what you promised because of that being "too good to be true". Huge rains? Faucet for every coin having 0.1/0.2-dollar value for 10 times? Referral system that has huge % makes me doubt too.
On top of those that I'd mentioned, are these newbie accounts that just woke up after a very long time. All of that sounds suspicious.
Probably paid accounts but it doesn't matter anyway we can test the site to see if it's good and fair, yes the faucet is a little bit too good to be true but maybe because they just started their website and wanted to attract players that's a good promotion actually. I will try and test out your website.
They might take down that faucet if they have a good number of users or they might stop doubling the faucet, so far the faucet is good it will make you log in daily to claim this is the second-best faucet I've to stumble, the first one was Betfury where you can claim every 30 minutes, the dice is good but you really need to deposit to extend your playing time and luck 48 sats will not do.
