Thanks @crpyto.piotr well thanks for having a look at my profile and i am glad i have met a true crypto enthusiasts who is so passionate about the blockchain technology.
Anyway Probit is a decentralized exchange platform that has the very best of security systems and user interface. there are so many exchange platforms probably over 1k as at the moment but most of these platforms are not secured enough to conduct your trading activities over there and i suggest Probit is among the few of the good exchange platform. I have also followed you and thanks for the upvote. I could really use that :)
