According to @balajis, crypto can be segmented into three eras with trading implications: Proof of Work from 2009 to 2017, Programmability from 2017 to 2025, and Privacy from 2025 to 203X, source: @balajis on X Nov 13 2025. For rotation screens, Proof of Work is represented by Bitcoin BTC which relies on proof of work consensus, source: Bitcoin whitepaper by Satoshi Nakamoto 2008. The Programmability era is led by Ethereum ETH which introduced general smart contracts that enable DeFi and NFTs, source: ethereum.org smart contracts documentation. The Privacy era maps to assets like Monero XMR and Zcash ZEC which implement privacy features at the protocol level, source: getmonero.org documentation and z.cash technology overview. Traders can use this timeline from @balajis as a catalyst to build a privacy narrative watchlist into 2025 focused on privacy coins and zero knowledge infrastructure that enables privacy preserving transactions and rollups, source: @balajis on X Nov 13 2025 and ethereum.org zero knowledge resources and z.cash technology docs.
