If I wanted to lose the money that I have then I would play a Dice game.
You mean sports books right? Not bitcoin casinos? Based from what you said, you wait a long time for each bet because you are gambling at sports books rather then dice games like you said. Since you also infer dice games are a quick and easy way to lose money. Though I agree, dice is a total money vacuum cleaner.
That's why I usually bet on sports, but the main con in sports betting is the house edge that is usually much more higher then dice games.
Bitcoin casinos is even worse, if you bet on slots machine , it can be totally rigged and you won't even be able to notice that.
Some casinos let you win at the first place to make you addicted so you will deposit more and more bitcoins.
