CME options can be used to hedge portfolio risk.
Casinos and sports gambling can at least be described as entertainment.
But betting and gambling on intra day financial events, what real world financial or social purpose does doing that serve?
If you think binary options can not be used to hedge, you know very very little about binary options.
As a fact, binary options are much better tool for hedging.
You are just too ignorant to talk on this topic.
In Casino gambling you have disadvantage because the rule decides that house get better odds.
In an exchange there is no house, anyone can take either side of a market.
You can be a market maker if you want.
If you always lose money, that is because you are bad in trading.
At least you are bad in trading binary options.
Binary options have wider spread because the odds decide the spread can only be that wide, or the other side will always win.
That means the wider spread ensures either side has equal odds.
But you need to take a proper strategy for binary, you can't trade it like you trade futures or stocks because it has wider spread.
Generally, after you take positions, you don't exit, because the spread is wider, so your odds get worse in most situation if you exit.
And betting on direction is usually a wrong way to trade binary options.
That is the most I can say.
If you always lose on binary, that is not because binary is bad, but because your way of trading binary is bad.
