I cannot remember when but I first heard about the project last year and even joined their telegram channel. Th project is basically riding on the popularity of David Chaum being one of the "legends" in cryptography. I kinda like their strategy of not rushing into finishing the token sale before but it appears they've become aggressive now with their signature campaign. Let's see how that works, it's rare seeing altcoin campaigns paying in bitcoin and at a good rate.

I guess they are only looking for long-term investors here and not some guys who will instantly dump their tokens after the token sale. I perfectly understand the investor's concern though, it's hard seeing your funds tied up to some altcoins when bitcoin starts pumping or dumping.
