Ionbanker is another exchange platform, that am very sure only few traders are aware of. Even myself, I got to know about this exchange some months back, when I was doing some researches on available Exchange.
Although, still available and active, this exchange is listed among the unrecognized exchange by the coinmarket Cap.
Iobanker exchange has no trading volume, and it is one of those exchanges with just few trading options. This features doesn't describe a quality Exchange. Also the privacy of this exchange is very minimal, with low security level.
This Exchange should not be regarded as a scam Exchange, as it is still available. It's just that the options available are very limited. Also , this exchange has low language support. As it support only two major languages, which makes it favorable for some people and unfavorable for others.
