Somebody knows when Zcash will launch and if there will be a ICO? Or only premine? how will they distribute?
And When Zcash launches, it will be a threat for coins like XMR and DASH, how do you guys see this?
The more concurrency in crypto privacy space the better. If zcash will provide superior technology and become better and safer option for privacy oriented users than xmr, than its good. Privacy wins.
Yes Z.cash may have a very slight edge under ideal conditions over Monero with ring CT in the privacy fungibility area; however there is a lot more to Monero than privacy fungibility.
There is the issue of blocksize and scaling that is currently plaguing Bitcoin. Monero has a viable solution for this. I have not seen a solution to this issue from Z.Cash at all. So privacy fungibility alone may not win. What good is a minuscule gain in privacy fungibility if one has to wait for many hours or even a day for a transaction to confirm as has recently been the case with Bitcoin.
There is also the fact that ringCT will bring multi signature transactions to Monero.
4.4 Ring Multisignature
Note that a simple version of a t of m of n ring-multisignature can be done with the MLSAG signatures. This allows a group of
m participants to create a multi-signature such that t out of m must sign for the signature to be accepted as valid, and in addition, it is signer ambiguous which m keys are the participants out of the n keys. ... An expanded writeup of the ring-multisignature is in the works
