To me, apart from the unique DeFi & NFT trend, new projects in the crypto market have nothing special because most of the ideas were born in 2017 during the ICO wave: the adoption of blockchain in healthcare. education, energy, transportation, internet ...
Currently, new projects start in 2 directions:
+ Copy other projects: for example DeFi, UniSwap => MoonSwap;
+ Implement old ideas on new platform: eg UniSwap => JustSwap of TRON & PancakeSwap of BSC;
The emergence of new projects is necessary for new blockchains, I think this will increase the competition and growth of blockchains, giving users more good choices in the future.
