@chen please consider using Kickstarter, if it doesn't have much worse conditions for you – a lot people seem to put more trust in it than in indiegogo.

A quick look at my backed (fully backed and "completed" – all of them were pretty likely to succeed from the available information) projects confirms this, at least for me: 20% failed projects on kickstarter; 25% successful projects on IG.
Also, KS doesn't seem to need a "IG vs KS" page linked on the footer of every page – maybe with good reason, maybe not.
