All I know is these new developers will keep making new projects because Cryptocurrency is a new industry and a young technology, the market is still open for all and every community and industry can create their own token and adopt the technology, so it's a hit or miss to the industry.
Old and new developers won't stop developing projects as long as they can. It's like a trial and error for them so if the project they have made fails, they can go back from the start and create a new project to sell again.
That will be the repetitive action that they'll simply apply for every project they make.
