Key Questions Answered

• •Layer One Consolidation: Ethereum captures institutional DeFi and real world assets while Solana dominates consumer crypto applications. Alternative layer ones struggle to retain capital after incentive campaigns end, with Unichain dropping from $1 billion to $100 million TVL after incentives stopped, demonstrating network effects favor established chains.
• •Robinhood Market Position: Robinhood ships 11 new products crossing $100 million run rate and strategically separates banking features from high-risk trading products into different apps. This intentional product design prevents user churn by keeping checking and savings accounts isolated from perps and options trading interfaces, targeting younger demographics effectively.
• •Token Investment Parity: Crypto tokens must reach parity with traditional equities through standardized accounting, quarterly reporting, clear token rights, and mature legal structures. Morpho's token structure and MetaDAO's framework demonstrate viable paths. Institutional capital currently flows to DATs, ETFs, and crypto equities instead of altcoins due to lack of proper reporting standards.
• •Prediction Market Competition: Polymarket positioned better than Kalshi for 2026 growth because Kalshi faces intense sports betting competition from FanDuel, DraftKings, and Robinhood partnerships. Over 50% of Kalshi's open interest concentrates on sports, while Polymarket maintains more diversified markets and stronger mindshare for exotic bet creation across categories.
• •Fat Wallet Thesis: Wallets and super apps capture 50 to 100 times higher take rates than underlying protocols, with Phantom charging approximately one dollar per transaction versus a few cents for Aerodrome or Uniswap. Wallets internalize stablecoin margins, MEV, and negotiate revenue kickbacks from protocols, shifting value from protocols to front-end aggregators controlling end users.
