A coin with big price swings is an OPPORTUNITY :-D
Lottery is an opportunity. Betting on horse races is an opportunity. Paying a visit to your local casino may be an opportunity. ZCoin isn't an "opportunity", it's one of the most advanced cryptocurrencies ever released, built upon rock-solid technology. Did you read the Zerocoin protocol whitepaper? Do you even know what a zero-knowledge proof is? All I can see here it's a vocal minority of
minus habens spreading FUD and misinformation that don't have the foggiest idea of all the benefits that truly anonymous cryptocurrencies can bring to everybody.
Does it make you feel superior to insult a well respected developper in Latin? Or anyone for that matter? Or in any language?
If you choose to criticize those you feel are inferiour you could reply to someone who, at least, resembles your strawman.
