I don't understand why gamblers think they're always going to win and it will be different from them ( Yes, yes I'm aware of the irony of having a gambling sig so sue me I'm earning coins from it
) but just look at the numbers even if you were to win once after investing hundreds of Bitcoins you'd still have an incredibly low chance of getting the money back that you put in regardless of the house edge percentage that was listed.
You'd honestly be better off if you threw you're money at altcoins if you're just in it to have some excitement but if you think for a second you can make money in gambling you're a moron, it should be done purely for entertainment hence why it's often called 'gaming'.
