Good projects don't just pop out of no where ,they take time to get built and it takes time to build the ideas developers wants to implement in every project
Good projects really need time to build what they have to build like building their own domain and thinking good ideas for the project's development. If good projects rush things for their project and pop out then the project will failed that is why they need effort and time to spend on making their platform as good as possible.
scam projects are the ones that pop out of no where
You are right about that scam pop out of no where. The reason why scam projects pop out of no where is because the person or group of people behind the scam project know that they could also have a project for scamming purpose only. Scammers can hire a website developer to create a website for the scam project site then the scammer will use a fake information such as contact number, a dummy telegram account for the scam project telegram group, fake team information and more of fake info that will make you think or believe that the project is legit and not a scam project.
