You give answer to some questions that “they are not regulated” and dismiss them for Regulated brokers in other countries which have no protection in the United Kingdom.
Do you gain anything from your recommendations?
No binary Options companies are regulated in the UK not even under the gambling regulations and binary is a gamble, that is why it is not taxed in the UK.
The sad part is that the UK Government allows this to happen without any regulation. I have pulled out after many scams about bonuses and you cannot even get your deposit money out from most of them. Do not touch Binary as even the biggest is a scam unless you are a gambler.
