Yep, it's sort of like Kickstarter! As of now: the crowdfunder specifies how much they need, in USD (or other fiat), and checks off which coins they want to accept. E.g. I need $10,000 worth of crypto and am willing to accept Litecoin and Ethereum. If they link up their Coinbase or GDAX account (via their APIs), they can convert the crypto to USD with one click at the end of the campaign, should they choose to do so.
One main difference with existing crowdfunding sites is that we're building an integrated bounty system, that will be somewhat similar to Amazon's affiliate marketing. You generate a link and share it, and if someone gives a donation after clicking on the link, you'll get a small cut. Cryptocurrencies are ideal for a system like this.
