Actually, in my view, bitcoin give us new and popular plate-forum of online gambling. Before bitcoin, i didn't think that online gambling have any future, But now bitcoin change the whole world of online gambling.
I am not saying bitcoin is not worth for gambling. I am just saying its not good for certain kinds of gambling like sportsbetting and poker where a bankroll management is an important part of the game. If you can't control your net worth due to the volatility, you are likely going to go down.
