ZERO CASH is not the same as ZCASH.
Two different currencies with two another DevTeams.
Kindly reminder.
Are you late to the party? We know.
Zcash is based on zerocash protocol.
Zcoin is based on zerocoin protocol.
They both have pros and cons. http://blog.zcoin.tech/zcoin-and-zcash/
Roger Ver is backing both. They are both legit.
They also both have "founder's rewards" of 20% for the first few years. Incidentally the coin in your signature also has a very significant dev/sponsor subsidy as well. I'm not necessarily against this a matter of course, but it just smells bad imo to launch what is nominally a currency and give 10-20% away to the developer(s) and their sponsors. How can you expect something to achieve real world traction and broad adoption when one guy or groups singlehandedly controls 5 or more % of the entire circulation that will ever exist? Obviously Bitcoin is kind of an exception here...
