I have seen so many non-scam projects that ended up being absolutely a disaster just because they couldn't do marketing properly. I was even part of a project that should have been basically a top 50 coin and right now it is not even in the top 3000 just because they lack funds and they couldn't do any marketing at all, they are good people building a great thing and nobody knows about it at all.
Yes, I agree with this. Lots of projects that really want to grow fall apart, but projects that are not serious can actually grow and grow faster. maybe because crypto is anonymous so it's hard for us to see if it's a real project or not. but I look more into marketing in terms of a project. even a few years ago, projects that only shared airdrops could grow even though they would eventually disappear slowly.
Well marketing is somehow executed by devs for short term period they only want to have an exposure to the community here so don't make it as a basis since any devs could pay some amount just to advertise their project. Maybe try to look at the developments and if they flow what is written in whitepaper since if they follow what they promise and contuously update the community about their project status with proof then we can say that we are in good one.
