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.
I've been making miners and developing coins for years so yes, I know my way.
You've taken it too seriously.
