It looks like we have run out of use cases in crypto space today since new developers have no new ideas anymore, they are left with repetitive ideas this days or ideas that will never survive on the blockchain, pls do not hesitate to correct me if you think I'm so wrong, so what's the use of many new projects every week? If you aren't tired well I am.
First I will say they aren't running out of ideas just that the pandemic is keeping many people at bay as the main thing that matters to everyone now is saving life. Also, you are right about repetitive ideas, many projects are fond of this hence the reason those type of projects don't last because since it is a repetition of what's already existing they find it hard adding new improvements which will keep it running. Also, some with this type of ideas can easily exit scam because they don't have anything to offer.
