X (Twitter) rolling out native crypto trading to 600M users. This is basically Coinbase embedded directly into the timeline - buy/sell without leaving the app. The infrastructure play here is massive: X already has payment rails approved in multiple US states, KYC systems in place, and now they're just plugging in crypto liquidity providers. Think about the UX shift: normies scrolling memes can impulse-buy $BTC mid-scroll. No app switching, no CEX signups. The real question is what custody model they're using and whether they'll support on-chain withdrawals or keep it custodial like Robinhood did initially. If Musk integrates this with X Payments and adds tipping in crypto, suddenly 600M users have hot wallets whether they realize it or not. Distribution >>> tech in crypto adoption, and X just became the biggest on-ramp that ever existed.
