I would be very sceptical of using any non-regulated broker, i cannot see why you would want to trade cryptocurrency on CFD either... The forex markets have a volume of 5.5 trillion a day, which dwarfs the cryptocurrency market. Dont get me wrong, i ran a business with a group of friends (and still do) in cryptocurrency, but it makes absolutely no sense to trade on CFD. Under absolutely no circumstances use a unregulated broker, even if they do claim to use the electronic communication network (ECN). Trust me, you will get burnt!
