Because I see Binary for what it is. Gambling. I have real trading accounts and trade for a prop firm. I know the markets better than most. Binary is my Roulette.
I'd care about regulation if I had $50k in an account but the occasional couple hundred bucks just for total amusement purposes, not too concerned.
I think the majority of these brokers use SpotOption and those idiots have their CYSEC license which is total nonsense but again, if you come at this knowing full well it's a casino masked with fancy financial terms and the attempts at getting their "clients" to believe they are in fact actually trading, it's more amusing than anything licensed or not.
Quite simply, binary options appear to be for people who think trading really is as easy as the "100% bonus" and "double your money in 60 seconds" ads make it seem. It's not. Even the best traders in the world are happy with 50/50 odds. The key is proper risk management and that is where these binary brokers take their cut. 100% when you lose, up to 80% back when we win. That alone says "casino".
