FundWise is hosting a casual side event during Berlin Blockchain Week featuring a friendly ping pong tournament with a $100 prize pool. Attendees will participate in a live shared-expense experiment, joining a FundWise group where food, drinks, prizes, and the community pool are tracked together. The event demonstrates how FundWise simplifies group spending through shared expenses, live balances, easy settlement, and clear receipts. No ping pong experience is required; the focus is on meeting builders, enjoying casual competition, and experiencing a real-world use case for crypto-native group spending.
