I feel like this has to be a troll or a spam post. OP asked about passive income and you suggested betting? Please feel free to expound on how one can bet passively and get any kind of passive income unless they own the site (the house always wins).
Passive income is income that always flows every day in a certain amount for an indefinite period, so obviously not for betting, but this is a kind of work that is mined every day through a strategy that is always implemented by everyone.
