Bitbank is not quite familiar name for me but if you are trying to do crowdfunding for something legal and have good future potential than you can try submitting your proposal in
https://bnktothefuture.com/ This. Bitstamp has used bnktothefuture.com for their crowdfunding campaign and I heard that they were quite successful in raising the funds they needed for their operations. There is also the ICO route but why start another ponzi? The whole community has had enough of scams already.
I thought you were using Indiegogo?
