Actually, many exchanges to date are just copycats. No originality and no special concept. Seamless blending with traditional online trading is the best concept trading platform so far.
Other exchange projects are just riding the crypto/ICO hype. Nothing unique or enticing.
A lot of scam project coming in too. People should always do their research and be aware of the key points in choosing the best exchange. I got my eyes set on IronX.
