Skepticism is essential because the crypto market is so harsh. Many projects were inflated and quickly evaporated from the market. That set off a wave of rapid collapse. Take a look at the projects on the market. Many projects need to increase the value of the token 100 or 1000 times before investors can recover their capital.
The next thing is the possibility of success, great effort to build. So only projects with a strong dev team can hope to succeed.
