ZCash could be the one to take the seat of the bitcoin or become a second coin as it offers the anonymity in transaction.
huge premine and you have to trust someone to maintain that privacy? that don't sound very promising to me. that's not gonna stop a stupidly high valuation of course. no one seems to care about crypto's principles if there's a smell of pump.
There is no premine.
https://forum.z.cash/t/final-zcash-mining-specifications/355Block time spacing/target spacing: Currently, in testnet, 2.5 minutes, with 12.5 ZEC reward per block. If there are any forthcoming multiplicative changes in block reward, they will be correlated to spacing such that zcash's rate of emission is fixed at an equivalency to Bitcoin's original emission curve, such that 50 ZEC are issued every 10 minutes. This emission curve is finalized, even though the block reward and spacing aren't yet.

However, to protect against instamining and accusations of miner collusion, the zcash team has decided not to apply the above rate of emission right from the genesis block. Instead, ZEC's emission will be subject to a slow start, where the emission curve will gradually ramp up to the full emission rate of 12.5 ZEC per block over the first 20,000 blocks. If there are further adjustments to the block spacing and reward, they will be in such a way that the following equation always remains true:
{# of slow start blocks} * {full block reward} = 250000
