I think you didn't understand my question correctly (my bad!).
I read about an exit pledge:
Q: If I understand correctly, waves is some kind of Uphold or Openledger with the main difference being the ability to crowdfund? What’s your plan in order to compete with Kickstarter ? Lower fees ?
A: WAVES is colored tokens blockchain platform, like NXT, having its own blockchain and integrated decentralized exchange. Our unique selling point compared to Kickstarter is the ability to exit your pledge. If you pledge some funds at kickstarter you have to wait for your product, you can’t transfer it to another user for example. Also you can start a campaign much faster on Waves then on Kickstarter, there are no moderators who approve your campaign. Of course the fees are much lower too, basically the fees are zero, compared to Kickstarter fees
