Unlike the Cyprus Securities and Exchange Commission, you will be more familiar with the FSA – the UK’s financial regulator – who Banc de Binary are now registered with. Full registration info here: http://www.fsa.gov.uk/register/firmBasicDetails.do?sid=314566
BDB are the first and only FSA regulated Binary Option company in the UK. MarketsWorld is regulated by the the Isle of Man Gambling Supervision Commission and not by a financial regulator.
By clicking the registration info link above and selecting “passports” you will see that the FSA have accepted BDB’s registration as an options provider. A step forward for the credibility of the binary options industry as a whole?
