As the comment period for the Crowdfunding rules has closed, it appears that the biggest concern of the commenters is the cost to initiate a crowdfunding campaign.
In particular, the requirement of audited financial statements, that could, per the SEC, cost up to $29,000, appears to have drawn the most wrath.
But other costs abound, including the payment of the portal, the escrow agent, money processors, counsel, finders, web ads, etc.
However, the commenters need to get real, in that even rewards-based crowdfunding has its costs. So, it seems that, regardless, you need a little money to make money.
