币界网报道：Messari researcher AJC believes that there are three reasons why Bitcoin Layer2 has opportunities: the Bitcoin network itself cannot provide smart contract functions or other functions provided by L2, which is different from Ethereum; there are no entrenched existing leaders in the Bitcoin ecosystem, and bridging BTC is an indicator of the degree of adoption. No single network holds more than about 30% of the total supply, and most networks hold much less than 10%, so new entrants can easily compete; BTC has the strongest economic foundation as a crypto asset. As StarkNet has begun to turn to Bitcoin, AJC expects that more Ethereum Layer2 will "abandon ship" and turn to the Bitcoin ecosystem in the future. [Wu said]
