I would like to add that I've already gathered 31 referrals to my name just by carrying the links in my own signature code:) I do not promote aggressively and I know I entered late,,, by the time I got in my site was famous already BUT I still got real people who clicked and play in just the short time of less than a year. For me it is really worth it to get a share of house edge.
i dont see tombola.game in the list .. it was one of my first investments in the crypto world 2 years ago.. they promsied that they will share theor profits with the share holders and promised to pay them with ether not their own token TBL.. it lasted 2 months but i supposed its dificult to grow in the bear market.. even if the idea is good.
I REMEMBER tombola,,, great idea too but like I should welcome you to the club of "I invested in this idea 2 years ago and it turned to shit"

Anyway, hope you learned my lesson too and kept your money in btc:)
