Not at all in favour of Binary Option trading. And in case some are really total desperate for it then the best possible way is through highly regulated and worthy brokers. I suggest this
https://fx-list.com, it’s a site with broker detailed list, which contains all broker from Forex/Crypto/Binary and one can pick the best through comparison easily here. When I say comparison, I mean towards going for regulated broker, and best if it’s from Australia but overall, it’s simply about a regulation from worthy authorities.
