PANews reported on April 11 that Mononaut, the anonymous developer behind the Bitcoin browser Mempool, said on the X platform: "If a Bitcoin L2 project does not support unilateral exit, then it is not a real L2 but a multi-signature one; if a Bitcoin L2 project has VC investors and its own tokens, then it is not a real L2, and such tokens are junk coins that pump and dump rather than L2. If a Bitcoin L2 project provides "reciprocal rewards" based on how much a user's friends deposit, then it is not a real L2, but a Ponzi scheme; if a Bitcoin L2 project is supported by an upgradeable Ethereum contract that can be controlled by a single company, then it is not a real L2, but a scam that may happen at any time; if a Bitcoin L2 project provides rewards to lock up users' tokens for as long as possible, then this is not L2, but Hex. 3.0; If a Bitcoin L2 project claims to be native to Bitcoin, but is actually just an Ethereum multi-signature contract, then it is not a real L2, but a deceptive scam. If a Bitcoin L2 project has no white paper or technical details, and only a 20-page document explaining how to deposit BTC and calculate future returns, then it is Bitconnect (a collapsed cryptocurrency lending platform) with a fake beard. "Ordinals founder Casey commented on this, saying, "This is the fact."
