Countries may want to ban crypto, but good luck with that - anyone can get a wallet and join the decentralized market.
Give me a full overview of Arbitrum (ARB) from a use case perspective:
- What problem does Arbitrum solve and who is it actually built for?
- What are its core use cases — DeFi, gaming, institutional, anything gaining real traction?
- Which protocols are thriving on it and what's pulling users and liquidity there?
- How does the ARB token fit into the ecosystem — what role does it actually play?
- What makes Arbitrum the go-to L2 over competitors for these use cases specifically?
- Any recent ecosystem growth or adoption worth highlighting?
Back everything with real numbers where possible. End with a sharp 2-3 line take on Arbitrum's real world impact so far.
