i will try to answer your question from my personal research,
firstly how is Abjcoin unique from the rest?; the consensus Algorithm which is proof of stake, with this algorithm, anybody can mine the Abjcoin just by having the core wallet and some Abjcoin. this feature will allow especially Africans and other countries of the world whose economy cannot power the proof of work algorithm because it is cost intensive. this alone makes Abjcoin Amazing. for African can now mine not leaving it to the people with heavy equipment which is the case bitcoin and others.
Secondly, Abjcoin trade market will provide a platform where people can transfer Abjcoin to various countries of the world and change it to their fiat currency anytime and day. This also will be something every merchants will embrace. for instance Nigerians have limitation buying goods from china, you send your supplier Abjcoin he changes it to his fiat currency in the trade market and send your goods this alone will help their currency appreciate against the dollar, something no other cryptocurrency has been able to do.
and finally i think the point above answers the next question.
please note this is my own opinion based on my personal research, i stand to be corrected if there are exception with the points stated above.
