Right, and since we are talking about myths, let's bust another one.
They say "the house always wins", in a sense that you will eventually go bankrupt, but in reality it's not what the house edge is doing. The house edge is there to make all the gamblers, in total, on a betting platform lose a small part from their bets. Almost nobody is losing exactly the house edge after, say, 100 bets. One particular bettor can be either in profit or loss, and it is uncertain, how many bets it can take to lose everything to the house. It can take 20 years of constant betting, or 200 years, nobody knows.
Basically, winning and losing will depend on the random algorithm that the house putted to their system for the bettors. Usually, for the cryptocurrency based games, the codes used is always audited to make sure that the game is fair. Meaning, we could trust the house from cryptocurrency gambling sites because they are verifiable. But in terms of physical casinos, it is hard to trust them since we don't know if they putted a tricked, let say, to always give the house an edge to long term betting.
