Crowd funding is the process of raising funds from a large number of people who each contribute a relatively small amount. Peer-to-peer (P2P) lending, where individuals lend money to unrelated borrowers without banks, is a major type of crowd funding. The document discusses the emergence, advantages, and types of crowd funding as well as P2P lending models, activities of P2P platforms, and examples of major crowd funding markets and platforms in regions like Europe, America, and others.
