There's a misconception about crowdfunding that says to be successful, you have to catch lightning in a bottle and create that elusive, viral hit. The "Ice Bucket Challenge," if you will.
While campaigns that raise tens of millions of dollars may be rare, crowdfunding is actually pretty formulaic. There are steps you can take to be successful, assets you need to raise a certain amount, and predictable results based on averages.
And that's a good thing! If crowdfunding success were a random occurrence, there would be no way to plan for success.
