To use Zcash, you must trust completely in the set up process and the six individuals involved in that process. This is a complete non-starter as far as I am concerned for any currency, least of all a currency which styles itself as a privacy currency.
As of their NU5 upgrade on May 31, Zcash no longer relies on a trusted setup [1].
