But these projects are just a mere imitation of the existing ones and chances of getting it to succeed will run short once there's a lot like you who also imitate the same project. Being the original creator is what makes you stand to all of them and that is not a given so you have to find your way to make it happen. Just like Satoshi did.
That is the act of standing out among the crowd.
No matter how many projects are, who pursue after the same target, some will be exceptional and if you want to be exceptional, you must bring out an extraordinary result.
To rate project as being successful, it must come out with something extra. Thatis, the team should add what was not added by others. No matter how little it is, it will definitely make a difference.
Some projects strove to make a difference and they achieved it. That is what success it.
Whoever does not achieve it or has not attained the desired goal, will know for sure that he needs to do more.
