Zcash could be good without 20% commission to investor team. Their 20% is too high, I avoid to buy this because I hate they dump on me.
We could say this is main reason why everybody hesitate to invest and waits for other opportunities.The ZCash team is slow, in my own opinion, when it comes to releasing constant upgrades and improvements (unlike other alts). I hope that soon, we would be able to see an official release of the GUI wallet, as well as cross-platform compatibility to gain a wider audience. Just sharing my thoughts. 
This is another one, not having GUI wallet is immature, this should be main task and should be worked on this day and night for that premine! I get feeling they are not sure what the are doing, this is not good climate for investors.I think it's worth investing because of anonymity.
XMR can give you more anonymity without premine risk.
