If the overall environment is not good, the public chain project party can first send a meme coin to test the ability of individual investors to accept orders. If the popularity is still good, the main coin can be issued accordingly; If the popularity is not good, delay the issuance of the main currency. That's how @ Tabichain used to play, and now @ Eclipse FND plays. And these heart wrenching tests are paid for by you, my friend.
