Re-evaluate

Coverage for claims 1 and 2 is extremely low. The recommended sources (Cointelegraph, CoinDesk, Stripe Blog) are likely to cover exchange listings and fintech API integrations, filling the gaps at minimal cost. Claim 3 already has partial coverage from S2, so no additional sources are strictly necessary. Total cost $0.006 is within remaining budget of $0.02.
