The success of an altcoin doesn't just depends on the bull market bro, perhaps it's not all altcoins that usually pumps during bull run. If an altcoin must be successful the CEO of the project have to promote their coins too before it can use the advantage of Bitcoin bull Run to pump. Don't expect every altcoin to pump this season because it will not happen.
Of course that is very true and relevant. The role of the development team in developing the project is also very important, meaning that the project will live and not stagnate without further innovation. This means that what is written in their white paper is really done by the team and fulfilled. Apart from that, there are also initiatives for many events to attract new users to come and buy the products.
