I just added Bitcoin Support to my adult crowdfunding site, and I noticed no other crowdfunding site seems to accept Bitcoin (The only two I could find: coinfunder.com and btc-funding.com both look dead) I can easily reuse parts of it to make a standalone crowdfunding site which accepts only Bitcoin. Is anyone interested?
Bitcoinstarter.com is about to re-launch. It was the 1st and oldest crowdfunding platform at the time. So there are others out there.
