That's how they are marketing their products because with participation in the block chain exhibition and block chain conferences will always get more awareness about the project. So it is always good to grab all the coins like F (X), Pundix, NPXSEM etc.
Yeah thats true, this project always develop and grab the coins is a good choice because now the price of the coins like F(X) and NPXS is cheap. I am only have NPXS and invest it for long term.
