Really there is nothing new to the table, so what is it about ?
How much you spend on marketing ?
Of course not. They could do all the marketing in the world and sell people on it and then do absolutely nothing wants to find a release comes and have the coin fall to s***. That is the making of a good scam not the making of a good project. It happens all the time. Marketing is something that is Port. But you have to back that marketing up with actually keeping the promises that you made.
The team, the relevance of the project and some other factors is what would make the coin successful. However, a pretty good project, with a good team and nice marketing can pretty much go a long way.
