Crowd funding is a relatively new option for raising money for projects, causes, and charitable assistance. The explosion of social media platforms naturally led to people using them to make money and ask for money. Concurrently, cynicism over potential scams has risen, often with good cause.
Most crowd funding applications have integration with social media and therefore getting the link shared is the key to raising money. Good descriptions of causes with broad appeal tend to do better. Reasonable target amounts are far more likely to be successful. Some platforms allow for incremental amounts t be donated. Some platforms require meeting the target in order for funds to be disbursed, thus allowing for some evolutionary feedback as to the worthiness of a given funding request.
