MRC markets also 

MRC- microCoin?

What is special about this coin if it is placed in a separate row?
And I see that this coin is under the patronage of this Exchange

and or course because it is alcurEX official coin.
Basically MRC is not more special or unique than any altcoins are.
Well maybe one unique option is payment reference for decentralized payment verification (for webshop plugins) but it is still unpublished.
