You have a point, what will make ab-chain successful is to have an active community and investors, to be able to have that they need to be more active and add more features if possible.
Exactly. What makes AB-CHAIN strong are the people who are really dedicated in developing this system as well as its supporters around the world. It doesn't matter if the idea itself is not unique. And by the way, they are now closer in reaching the soft cap.
If the idea isnt unique then they have to compete with existing competitors who in this case are the GIANTS of advertising Google Adsense (and other smaller fish)
New projects with ico will surely finds where to advertise their project so I am sure they will consider ab-chain knowing that ab-chain is really gaining high popularity now.
