Most of us know there are some brokers on the market these days that claim to be based in the UK and are FCA-regulated.
What some people living in Britain may not know is that bins isn't covered by the FCA (although they are likely to in the future). In fact, the UK government presently considers bins as betting and, as such, regulation for that falls under the Gambling Commission.
Here's a link to the GC web page on the subject for anyone that cares.
Here's an interesting paragraph about bins regulation in the UK that I thought I should point out:
The Gambling Commission regulates operators offering binary options if they have remote gambling equipment located in Great Britain.
Licensed operators are required to make it clear, on their websites, that they are licensed by the Commission, whether or not they hold other licences issued by other regulators. You can check our licence register to be sure you are gambling with a licensed operator.
Unlike other forms of remote gambling, operators offering binary options with all of their remote gambling equipment located outside Great Britain do not have to be licensed by us. This means that, although consumers in Great Britain are able to use the services provided by these operators, we do not regulate them. Such operators may, however, be regulated and/or licensed in other jurisdictions.
I guess the point I'm trying to make is this: just because you live in the UK and you use an FCA-regulated bins broker, that doesn't mean your ass is covered if the broker is dodgy. At least, not until the laws here change...
As a side note, when bins finally gets covered by the FCA, it would be interesting to see if we Brits have to pay capital gains tax or income tax on bins like you do with forex trading...
