If you ever play on big casino like bc.game or stake.com, you will understand there is always some kind of "maximum winning".
Thus you won't able to become millionaire by playing on that site alone for that reason.
So what you can do is maximize your earnings from the maximum winning and wait for next year and keep repeating it.
If not then keep using your family, friends and relatives to maximize your profits and also help them win some.
Asking strangers on a forum and not using your own friends and family ? Call that a work of humanity ? Sounds fishy !
