For around the last year I have not seen one single coin that has been newly listed worth investing in most coins today are copies of others which have failed.
Creating a new tech or innovation was so difficult and it's not easy as you said that dude. So many coins were doing more and more improvements from the old protocols and this is totally needed to be used as a sustainable development to make sure crypto will always evolve from time to the time.
At the same time they often claimed to have developed innovative protocols that actually weren't really that innovative because they gave up on some of the other core values like trading efficiency for security or other trade-offs. An innovation to me is at least in the area of crypto when you can keep as much as possible the core values of decentralization and what comes along with it while improving parts of it like scalability. When the first coins came and said hey we can do 1,000,000 tx per second it turned out that they were almost fully centralized. That is not innovation to me.
