I believe people are getting smarter regarding cryptocurrencies and finally start doing some research before buying anything. In my opinion, crypto tokens without a strong project and team behind them will no longer get as much attention in the future. One strategy before any token purchases will be DIOR, for example I am following this project since July
https://bitcointalk.org/index.php?topic=5344159.msg57244402#msg57244402 , and I will definitely wait until round 2 of public sale just to see the public reaction to it
No one can give exact number or percentage because current bull run is pumping for few projects those was expecting to die in near future, but this all is just temporary because currently we have too many shit coins and projects those are really need to die very quickly as pump and dump devs playing their own games for taking profit from innocent investors, and we cannot stop these shit coins and projects, so these will be reappeared again in future and give some hype in any face like we have years ago in 2017 just need some good education for newbies and investors to understand this all for safety of funds.
