When does a mature coin like ZEC need to wait for developer response?

Anyone see this Twitter:    https://twitter.com/WhalePanda/status/950710106760597504
So... $ZEC offline on both @BittrexExchange and @Poloniex 🤔"awaiting dev response"


In the world full of scam and sham coins, which zk-snarks privacy coin is best.   Which one has the spirit of the original bitcoin?  The easy answer is BitcoinZ!

BTCZ = community coin, no premine, no dev fund, and no founders reward.

Look at all of these sham coins below with zk-snarks and tell me why anyone would want to own them.

ZEC = 20% founder fund WTF
ZCL = ZEC fork, TBD fork to BTCP
ZEN = ZCL fork, 8.5% treasury fund
VOT = Entire float 4.54% premine
HUSH = Premine, Zdash rebrand, airdrop/fork to BTCH
KMD = Premine and ICO 100M coins
