Ordinals founder: Except for the Lightning Network, all other Bitcoin L2s are "castles in the air"

Odaily News Casey, founder of Ordinals and Runes protocols, said in a recent interview with Wu that when discussing whether Bitcoin needs L2, except for the Lightning Network, all other Bitcoin second-layer solutions are "castles in the air" and none of them have users, good implementations or clear paths to success. It is wise to ignore them before they are actually implemented. (Wu said)
