Original title: No Black Swan Events, Four Atypical Guesses About the Culprit Behind Bitcoin Overselling
---------------------------------------------------------------
A black swan-style crash has arrived, but we haven't seen where the black swan is, which is even more unsettling.
Almost without warning, Bitcoin suddenly plummeted, entering its third-largest oversold zone in history, causing both long positions to collapse and psychological barriers to fall. This has left the market perplexed...

The absence of black swan events suggests there may be other reasons for Bitcoin's current oversold condition.

Bitcoin ($BTC) has recently gone through a sudden shift on Bithumb, a well-known South Korean crypto exchange. In this respect, the $BTC/KRW trading abruptly plummeted over 10% below the worldwide ave...

What is Arbitrum Orbit?
Orbit is a framework by @OffchainLabs &amp; supported by the Arbitrum Foundation that allows devs to launch their own blockchain networks—Orbit chains—customized for any use case.
It’s all about flexibility, scalability &amp; interoperability. https://x.com/i/web/status/1899641790027931859

How Orbit Chains Work
Orbit chains are built on top of Arbitrum One or Nova (L2s) &amp; can also settle on other Ethereum-aligned chains via the Orbit Expansion Program.
They can function as either:
🔹L2s (settling on Ethereum)
🔹L3s (settling on an L2 like Arbitrum One) https://x.com/i/web/status/1899641792041197745 

Key Features of Orbit
🔹Customization: Devs can tweak privacy, governance, gas tokens &amp; more.
🔹Scalability: High TPS, low fees, inherits Arbitrum’s security.
🔹Tech Stack: Powered by Nitro + supports Stylus (Rust, C, C++).
🔹Permissionless: Anyone can launch a chain, no… https://x.com/i/web/status/1899641795090530383

Orbit Chains = Full Customization
Unlike general-purpose blockchains, Orbit lets you:
🔹Pick your gas token (not just ETH, use any ERC-20)
🔹Choose governance models &amp; permissions
🔹Optimize for gaming, DeFi, NFTs, or anything else https://x.com/i/web/status/1899641797250609201

Tech Stack
Orbit chains run on Arbitrum Nitro, which includes:
🔹Fraud proofs for security
🔹Data compression for efficiency
🔹EVM compatibility for seamless dApp deployment
Plus, Orbit benefits from upgrades like Stylus (multi-language support) &amp; BoLD (faster validation). Read… https://x.com/i/web/status/1899641799276364261

Rollup vs. AnyTrust
Orbit chains can be either:
🔹Rollup Chains – Settle directly on Ethereum or an Arbitrum L2. Best for security &amp; decentralization.
🔹AnyTrust Chains – Use a small committee for data availability. Lower fees, ideal for gaming/social apps. https://x.com/i/web/status/1899641801306443797

Real-World Examples
Orbit is already powering a growing ecosystem of projects, including:
🔹@xai - Gaming L3 for massive scalability.
🔹@RariChain - NFT L3 with royalty enforcement.
🔹@DeriProtocol - DeFi L3 optimized for trading.
🔹@apecoin - Built for the ApeCoin ecosystem.

Orbit’s Growth So Far
🔹30+ Orbit chains have already hit mainnet.
🔹$200M+ Total Value Locked (TVL).
🔹Rapid ecosystem expansion, with more projects deploying soon.
The momentum is just getting started. 🚀 https://x.com/i/web/status/1899641805995692385
