Countries may want to ban crypto, but good luck with that - anyone can get a wallet and join the decentralized market.

Give me a clear, data-backed overview of Arbitrum (ARB) focused on real usage and adoption - not narratives. Break it down simply: What problem Arbitrum actually solves and who is using it today What use cases are реально working (DeFi, perps, etc.) with real numbers (TVL, users, volume) Which protocols are driving most activity and why liquidity stays on Arbitrum What role ARB token actually plays - does it capture value or just governance How Arbitrum compares to Optimism, Base, and Solana in real usage Any recent growth or adoption signals that actually matter Keep it practical, avoid generic explanations, and use real metrics where possible. End with a short conclusion: Is Arbitrum really strong, or replaceable?
