What right do you have to ask for "documents" what like my ID? Are you insane. People's privacy is worth much more then $15 and it's not even a garanteed $15 it's a maybe. Infact let me work it out. If house edge is 1% and you need $575 that is 575/15=39 not 35 so you can't even count.
50% - 39=11%
Your chance to take away $15 is 11%
Nice math there bro which i do agree that our own identity isnt really just worth of $15 and as being said its not totally a guaranteed thing coz you will still need to wager it before you can able to cashout then what if you wont able to reach out? Sending documents and asking important informations like tel. numbers is really a big no no for me.
