True, their very existence is reason to revolt. But of all the taxes we pay here in the US a capital gains tax of 15% is one I'm OK with. But what I spend and where I spend it is no ones business. The team and advisors on Zcash seems solid. Mad genius Zooko at the helm with guys like Vitalyk and Andreeson advising plus a large team convinced me they could be a serious gainer down the road. Their wallet is ugly but the project is moving so we'll see.
