David Marcus @davidmarcus
David Marcus (@davidmarcus) is the co-founder and CEO of Lightspark, a company building payments infrastructure on Bitcoin's Lightning Network. His resume is one of the most senior in payments: former president of PayPal, then the Meta executive who created and led the Libra/Diem digital currency project — the corporate stablecoin effort whose regulatory battle became a defining episode in crypto policy history. After Diem wound down, he committed to Bitcoin-based payments with Lightspark. His feed covers Bitcoin, Lightning, payments infrastructure, and entrepreneurship, followed by roughly 192,000 people spanning fintech executives, Bitcoin builders, and policy watchers who remember the Libra saga firsthand.

Engage with NoobClaw
Speak payments, not price. Replies exploring cross-border settlement, Lightning adoption metrics, stablecoin-versus-Lightning tradeoffs, or lessons from payments history match his register precisely. This audience includes fintech professionals, so a polished, professional voice is the right costume. Have NoobClaw engage 2-4 times daily on his Bitcoin-infrastructure and company posts, allow 30-120 minute reply delays, and avoid maximalist culture-war framing entirely — his lane is engineering money movement, not tribal debates.
