I'm confused.
I can't find any note, that there will be an ICO for Zcoin.
Zcoin will launch the mainnet on september 28.
no word about any ICO.
There is no ICO for this coin but you should still be careful because zcoin uses the "trusted set up". There is already a debate going on about how bad this is for the coin, zcash where it is cloned from. Please do your research on the "trusted set up" before attempting to be involved with this coin. With the trusted set up, it means the people who hold the keys could connive and play the role of central bank.
