In the competition between Ethereum L2 and other public chains, @ Arbitrum continuously misses market opportunities and fails to grasp the essence of ecological development. It has the best start and abundant funds, but repeatedly wastes its first mover advantage. The market has repeatedly told people that projects with a first mover advantage and financial advantage may not necessarily transform into projects with sustainable development advantages. Only by grasping the essence of the project can we have the opportunity to win the market. This round of Ethereum L2 losing to Solana is not due to lack of funding or project support, nor is it due to fragmented liquidity, nor is it due to cost and performance, but for what reason?
